Thorlabs' Manually Adjustable Rigid Stands provide additional flexibility and adaptability to any microscopy application. Each stand has a slim profile that consumes a minimal amount of space in and around the optical path. This leaves ample approach room for any objectives, micromanipulators, a condenser, and other equipment, making it easy to work around the setup. Each post offers 360° rotational adjustment allowing a mounted component to be easily positioned within the imaging system. Additionally, with accessories designed for slides, petri dishes, recording chambers, micromanipulators, well plates, and general electrophysiology applications, our rigid stands can be used in virtually any setup. Thorlabs also offers a motorized rigid stand for precise, repeatable height adjustment.
DIY or Preconfigured Stands
Manual rigid stands may be purchased preconfigured or as separate components, as shown in the table to the right. Each stand consists of a post holder, post, and rail or insert holder; a variety of inserts are also available, including microscope slide holders and breadboards. We also offer preconfigured stands at select heights, available with dovetail rails or rectangular insert holders.
Translation Stages
We also offer two types of manual translation stages that provide 25 mm of translation in one or two horizontal axes and are compatible with our manual rigid stands via the MPA1(/M) adapter plate. The manual stages with quick connect feature dovetails that allow users to construct their own multi-axis stage, while the self-contained manual stages offer a more compact footprint. Thorlabs also manufactures motorized translation stages for these rigid stands that enable 1" of horizontal travel in one or two axes when used with the PLST(/M) top plate.
For sample holders that attach directly to the DIY Cerna® microscope body, please see our manual and motorized XY stages.
Post Adjustment Features
As illustrated in the animation below, a quick-release clamp locks and unlocks the post. The post collar included with the post holder features an alignment pin can be used to maintain the post's height during its rotation. The alignment pin acts as a hard mechanical stop that lets you quickly return to a previously set angle. To raise or lower the post within its given vertical range, it is necessary to loosen the collar, which is locked onto the post using a cap screw that accepts a 4 mm (5/32") balldriver. Each post is housed inside a red post holder, which is compatible with 66 mm rail accessories and optomechanical mounts.

Building a Cerna® Microscope
The Cerna microscopy platform's large working volume and system of dovetails make it straightforward to connect and position the components of the microscope. This flexibility enables simple and stable set up of a preconfigured microscope, and provides easy paths for later upgrades and modification. See below for a couple examples of the assembly of some DIY Cerna microscopes.
DIY Cerna Design and Assembly
Walkthrough of a DIY Microscope Configuration
This DIY microscope uses a CSA3000(/M) Breadboard Top, a CSA2001 Dovetail Adapter, our CSA1001 and CSA1002 Fixed Arms, and other body attachments and extensions. These components provide interfaces to our lens tube and cage construction systems, allowing the rig to incorporate two independent trans-illumination modules, a home-built epi-illumination path, and a custom sample viewing optical path.
The simplicity of Thorlabs optomechanical interfaces allows a custom DIY microscope to be quickly assembled and reconfigured for custom imaging applications.

 (posted 2021-10-21 21:03:41.95) I wish to mount the base of MP150 on the XT95SD-500 one-side rail via XT95P12/M - Rail plate. It is possible ? If cannot, could you advice other methods. Thank you. cdolbashian
 (posted 2021-10-29 11:14:09.0) Thank you for reaching out to us at Thorlabs regarding the compatibility of these parts. Unfortunately these two parts are not directly compatible, however I have contacted you directly to find a solution! Stepan Kortus
 (posted 2021-06-08 10:16:44.28) The MP200 drawing says it has the holes for mounting to tabletop with distance 50.8 x 75.2-85.3 mm. Can be the MP200 directly mounted to the metric tabletop with M6 holes distributed in 25mm grid layout? Thank you. YLohia
 (posted 2021-06-15 11:05:39.0) Hello, thank you for contacting Thorlabs. The MP200 has counterbored slots for mounting. Therefore, you will have enough slack (or tolerance) for using M6 capscrews in a 25 mm hole spacing. jtdo
 (posted 2019-03-08 17:54:35.08) Is the red part of the rigid stand the same as a 66mm optical rail? And if so, can I mount the rail carriage (XT66P2) to it? Thanks! mmcclure
 (posted 2019-03-11 01:58:11.0) Hello, thank you for contacting us. The rigid stands' red post holder is compatible with our 66 mm optical rail components and accessories, including the XT66P2 rail carriage. We will update the webpage presentation to make this compatibility more apparent. timothee.labouret
 (posted 2017-06-26 17:01:08.433) Hi,
I have a question regarding the MP200. Is the post removable from the post holder in order to extend it with another 1.5" post ? Also, is the platform removable from the post to yield a normal 1.5" post ? Thank you for your support. Regards tfrisch
 (posted 2017-06-27 04:37:05.0) Hello, thank you for contacting Thorlabs. The post is removable and a different 1.5" diameter post can be used. |

Elements of a Microscope
This overview was developed to provide a general understanding of a Cerna® microscope. Click on the different portions of the microscope graphic to the right or use the links below to learn how a Cerna microscope visualizes a sample.
Terminology
Arm: Holds components in the optical path of the microscope.
Bayonet Mount: A form of mechanical attachment with tabs on the male end that fit into L-shaped slots on the female end.
Bellows: A tube with accordion-shaped rubber sides for a flexible, light-tight extension between the microscope body and the objective.
Breadboard: A flat structure with regularly spaced tapped holes for DIY construction.
Dovetail: A form of mechanical attachment for many microscopy components. A linear dovetail allows flexible positioning along one dimension before being locked down, while a circular dovetail secures the component in one position. See the Microscope Dovetails tab or here for details.
Epi-Illumination: Illumination on the same side of the sample as the viewing apparatus. Epi-fluorescence, reflected light, and confocal microscopy are some examples of imaging modalities that utilize epi-illumination.
Filter Cube: A cube that holds filters and other optical elements at the correct orientations for microscopy. For example, filter cubes are essential for fluorescence microscopy and reflected light microscopy.
Köhler Illumination: A method of illumination that utilizes various optical elements to defocus and flatten the intensity of light across the field of view in the sample plane. A condenser and light collimator are necessary for this technique.
Nosepiece: A type of arm used to hold the microscope objective in the optical path of the microscope.
Optical Path: The path light follows through the microscope.
Rail Height: The height of the support rail of the microscope body.
Throat Depth: The distance from the vertical portion of the optical path to the edge of the support rail of the microscope body. The size of the throat depth, along with the working height, determine the working space available for microscopy.
Trans-Illumination: Illumination on the opposite side of the sample as the viewing apparatus. Brightfield, differential interference contrast (DIC), Dodt gradient contrast, and darkfield microscopy are some examples of imaging modalities that utilize trans-illumination.
Working Height: The height of the support rail of the microscope body plus the height of the base. The size of the working height, along with the throat depth, determine the working space available for microscopy.
Cerna Microscope Body
Click to Enlarge
Body Details
Microscope Body
The microscope body provides the foundation of any Cerna microscope. The support rail utilizes 95 mm rails machined to a high angular tolerance to ensure an aligned optical path and perpendicularity with the optical table. The support rail height chosen (350 - 600 mm) determines the vertical range available for experiments and microscopy components. The 7.74" throat depth, or distance from the optical path to the support rail, provides a large working space for experiments. Components attach to the body by way of either a linear dovetail on the support rail, or a circular dovetail on the epi-illumination arm (on certain models). Please see the Microscope Dovetails tab or here for further details.
Illumination with a Cerna microscope can come from above (yellow) or below (orange). Illumination sources (green) attach to either.
Illumination
Using the Cerna microscope body, a sample can be illuminated in two directions: from above (epi-illumination, see yellow components to the right) or from below (trans-illumination, see orange components to the right).
Epi-illumination illuminates on the same side of the sample as the viewing apparatus; therefore, the light from the illumination source (green) and the light from the sample plane share a portion of the optical path. It is used in fluorescence, confocal, and reflected light microscopy. Epi-illumination modules, which direct and condition light along the optical path, are attached to the epi-illumination arm of the microscope body via a circular D1N dovetail (see the Microscope Dovetails tab or here for details). Multiple epi-illumination modules are available, as well as breadboard tops, which have regularly spaced tapped holes for custom designs.
Trans-illumination illuminates from the opposite side of the sample as the viewing apparatus. Example imaging modalities include brightfield, differential interference contrast (DIC), Dodt gradient contrast, oblique, and darkfield microscopy. Trans-illumination modules, which condition light (on certain models) and direct it along the optical path, are attached to the support rail of the microscope body via a linear dovetail (see Microscope Dovetails tab or here). Please note that certain imaging modalities will require additional optics to alter the properties of the beam; these optics may be easily incorporated in the optical path via lens tubes and cage systems. In addition, Thorlabs offers condensers, which reshape input collimated light to help create optimal Köhler illumination. These attach to a mounting arm, which holds the condenser at the throat depth, or the distance from the optical path to the support rail. The arm attaches to a focusing module, used for aligning the condenser with respect to the sample and trans-illumination module.
Epi-Illumination Modules | Breadboards & Body Attachments |
Brightfield | DIC | Dodt | Condensers | Condenser Mounting | Light Sources |
Light from the sample plane is collected through an objective (blue) and viewed using trinocs or other optical ports (pink).
Sample Viewing/Recording
Once illuminated, examining a sample with a microscope requires both focusing on the sample plane (see blue components to the right) and visualizing the resulting image (see pink components).
A microscope objective collects and magnifies light from the sample plane for imaging. On the Cerna microscope, the objective is threaded onto a nosepiece, which holds the objective at the throat depth, or the distance from the optical path to the support rail of the microscope body. This nosepiece is secured to a motorized focusing module, used for focusing the objective as well as for moving it out of the way for sample handling. To ensure a light-tight path from the objective, the microscope body comes with a bellows (not pictured).
Various modules are available for sample viewing and data collection. Trinoculars have three points of vision to view the sample directly as well as with a camera. Double camera ports redirect or split the optical path among two viewing channels. Camera tubes increase or decrease the image magnification. For data collection, Thorlabs offers both cameras and photomultiplier tubes (PMTs), the latter being necessary to detect fluorescence signals for confocal microscopy. Breadboard tops provide functionality for custom-designed data collection setups. Modules are attached to the microscope body via a circular dovetail (see the Microscope Dovetails tab or here for details).
The rigid stand (purple) pictured is one of various sample mounting options available.
Sample/Experiment Mounting
Various sample and equipment mounting options are available to take advantage of the large working space of this microscope system. Large samples and ancillary equipment can be mounted via mounting platforms, which fit around the microscope body and utilize a breadboard design with regularly spaced tapped through holes. Small samples can be mounted on rigid stands (for example, see the purple component to the right), which have holders for different methods of sample preparation and data collection, such as slides, well plates, and petri dishes. For more traditional sample mounting, slides can also be mounted directly onto the microscope body via a manual XY stage. The rigid stands can translate by way of motorized stages (sold separately), while the mounting platforms contain built-in mechanics for motorized or manual translation. Rigid stands can also be mounted on top of the mounting platforms for independent and synchronized movement of multiple instruments, if you are interested in performing experiments simultaneously during microscopy.
