The scanner is installed by threading a brass adapter into the microscope's objective holder with the included spanner wrench and tightening a flexure clamp around the adapter with the included 5/64" (2 mm) hex key. The objective is attached to the scanner using a separate brass adapter and flexure clamp.

Features

  • Fast Acquisitions and High Frame Rates Enabled by 25 ms Typical Settling Time
  • Maximum Clear Aperture of Ø29.0 mm Supports Large-Field-of-View Objectives
  • Capacitive Feedback Sensors Provide Resolution Down to 1 nm and Help User Actively Compensate for Drift
  • Quick-Release Flexure Clamps Allow Fast Objective Exchange
  • Compatible with Upright, Inverted, and Rotating Microscopes
  • Standalone Kinesis® and APT™ Interfaces, ThorImage®LS Integration, and Control via External Voltage
  • Software Permits Easy Tuning for Different Objective Weights

The PFM450E Piezo Objective Positioner is designed for fine focus adjustment and high-speed Z-stack acquisition. Engineered for compatibility with Thorlabs' Bergamo® III Multiphoton Microscopes, our Confocal Imaging System, our Cerna® Microscopy Platform, and third-party microscopes, it bypasses the relatively slow stepper motors built into microscopes in order to quickly obtain scans of 3D volumes. Built-in capacitive feedback sensors allow the module to provide 1 nm resolution in open-loop operation and 3 nm resolution in closed-loop operation, enabling active compensation for short- and long-term drifts.

With a clear aperture of up to Ø29.0 mm and a maximum load of 500 g (1.1 lbs), the piezo objective holder easily accommodates the large-field-of-view objectives commonly used in multiphoton and confocal microscopy. In order to permit easy switching between objectives, the piezo stage is attached to the microscope and objective by independent adapters. This design choice allows the objective to be removed without disconnecting the rest of the assembly. Adapters are available for M32 x 0.75, M27 x 0.75, SM1 (1.035"-40), M26 x 0.706, M25 x 0.75, and RMS (0.800"-36) threads.

Each scanner is shipped with a piezo controller that has been factory calibrated to the specific scanner. Objective positioning is supported through the included standalone Kinesis and APT GUIs, our ThorImageLS image acquisition software, or an externally supplied control voltage. See the Software & External Control tab for more details. The controller offers USB and RS-232 interfaces for computer control; a BNC input for sine, sawtooth, and square wave drive signals; and a BNC output that gives either positioning feedback from the scanner's built-in capacitive sensors or a signal proportional to the piezo drive voltage. In addition, a DB15 connector provides signals that can be used for synchronization with external equipment.

The scanner can be driven using the included standalone Kinesis® GUI, the legacy APT™ GUI, our ThorImage®LS software for Bergamo® III and confocal microscopes, or an externally supplied control voltage. In addition, a DB15 connector provides signals that can be used for synchronization with external equipment. Complete details on control are available in the PFM450E manual for Kinesis and APT (PDF links).

Open-Loop Operation vs. Closed-Loop Operation
There are two operating modes for positioning the objective: open loop and closed loop. In open-loop operation, which supports a travel range of 600 µm ± 10%, the user controls the piezo drive voltage (in V). The applied drive voltage corresponds to some amount of objective displacement. For piezoelectric materials, this displacement does not depend linearly on the applied voltage: it exhibits nonlinearity and hysteresis. It is therefore not straightforward to position the objective by choosing the drive voltage. The scanner's built-in capacitive feedback sensors measure the objective displacement with 1 nm resolution in open-loop operation.

In closed-loop operation, which supports a travel range of 450 µm, the user directly controls the objective displacement (in µm). The built-in capacitive feedback sensors measure the objective displacement with 3 nm resolution in closed-loop operation.

APT Loop Tuning tab. The default settings are for a 150 g objective. As a rule of thumb, for a 2X increase in objective weight, divide all PID parameters by 2 and divide all notch filter settings by the square root of 2. The default settings can be restored in the General tab.

Standalone Kinesis and APT GUIs
The Kinesis and APT GUIs support both open- and closed-loop operation. The piezo drive voltage or objective displacement can be directly typed in, changed by dragging the output knob (APT only), or incremented or decremented in fixed, user-defined amounts.

In addition, the GUIs enable software-based PID loop tuning. The default settings are designed to provide stable operation for most small- and medium-sized objectives, but fine tuning the PID loop helps account for the specific microscope and objective in use in the experiment, reducing positional overshoots and ringing about the commanded objective position.

Screenshots are shown to the left.

ThorImageLS Image Acquisition Software
ThorImageLS supports closed-loop operation. It allows the movement of the objective scanner to be controlled from the same interface as Thorlabs' Bergamo III and confocal microscopes, greatly simplifying experimental integration. For convenience, controls for the piezo objective scanner are found in both the Capture Setup and Capture tabs. Screenshots are shown to the right.

Externally Supplied Control Voltage
In this mode, the scanner supports both open- and closed-loop operation. The voltage is applied using the external input BNC connector on the controller. In open-loop operation, a 1 V change in input voltage results in a 15 V change in drive voltage, while in closed-loop operation, a 1 V change in input voltage results in a 45 µm change in objective displacement. The drive voltage or objective displacement that is determined by the input voltage is added to the value that is set in the APT GUI. If this sum would result in a drive voltage outside the -30 V to +150 V range, those limits will not be exceeded.

The external input BNC connector is typically used with sine, sawtooth, or square drive signals. The maximum frequency of the signal that should be applied depends upon the waveform. For large periodic waveforms (i.e., sine waves that provide >200 µm of total displacement), the recommended drive frequencies are:

  • ≤25 Hz for Loads up to 150 g,
  • ≤20 Hz for Loads from 150 g to 250 g,
  • ≤15 Hz for Loads from 250 g to 400 g, and
  • ≤10 Hz for Loads from 400 g to 500 g.

For staircase waveforms with step sizes up to 50 µm, the minimum time between steps can be as small as the 25 ms typical settling time.

DB15 Connector
For photostimulation, electrophysiology, and optogenetics applications, the DB15 connector on the controller provides several electrical signals that can be used to synchronize the movement of the piezo objective scanner with other equipment, such as multiphoton imaging lasers, patch clamp electrodes, and LED light sources. Details on this connector are available in Appendix A.2 of the manual (PDF link).

Hi, I would like to extend the cable connecting the PFM450E scanner and controller by 3m so that the total length is 5m. If 5m is too long, we could also extend by 1m, so the total length is 3m. Can you please recommend an extension cable for this?

Clemens Alt  (posted 2024-01-08 10:47:21.993)
Good morning, I am looking for a microscope objective positioner. But for our application, the axis of light propagation is horizontal, i.e., the objective is mounted horizontally and needs to move horizontally to shift the focus. Our objective weighs almost 300 g and is 90 mm long, so the center of gravity would be 10s of mm away from the mounting ring. Can the PFM450E support such a load? Thank you.
cstroud  (posted 2024-01-10 11:16:15.0)
Thank you for your enquiry. The maximum load for this stage is 500g in any orientation, and we recommend that the centre of mass is as close as possible to the stage. I will reach out to you directly to discuss your particular application.

Hi there, I've been using the PFM450 for a couple of year now, but today it started making a crunching noise, followed by an error showing up on the controller, without any movement. The controller is probably fine, but I fear the piezo objective controller has burnt out. Firstly is there any recommendations for remedying it, but more than likely what I'm asking is it possible to price just the objective controller alone, not the piezo controller box? Best regards, Charlie

Response from Daniel at Thorlabs. I will reach out to you directly to discuss the best options to remedy this for you as the stages are paired with their controllers.

Dear engineers of Thorlabs, Hi, our labratory recently bought your product PFM450E, Piezo Objective Scanner and paired Controller. We have two inquiries about your products. At first, Is there any way we can see measured distance in three-digits nanometer level in closed loop mode? We are using external signal for input voltage of controller in closed loop mode. We want to see corresponding position data in more precise level such as 32.358 micrometer not 32.36 micrometer. Secondly, can we take position data through your software(APT), or in any other ways? We are using external stepped voltage signal as a controller input. So we want to acquire position data corresponding to each step. Thank you.

Hello, I'm trying to figure out what this system uses as a feedback signal for detecting the substrate. Does it use a camera image? How can I set this up in a system where I replace the camera signal during measurements with an emission signal, that does not correspond the topography of the sample? Cheers, Fredrik
cwright  (posted 2021-06-02 08:32:14.0)
Response from Charles at Thorlabs: Thank you for your query. The PFM450E does not have an inbuilt way of detecting a substrate but the controller used in the PFM450E has the option of being controlled by an external source supplying a voltage of -10V to +10V, which is summed with the software demanded position. If using the external input alone then 0V to +10V would correspond to the full travel range of the device. This allows the PFM450E to be controlled by another device which could detect the substrate.

It would be nice to have a way to store the PID constants for different objectives into the system. Having to re-enter them from a notebook every time the objective is changed works but some sort of memory or storage (even in the app) would be nice.
