Features

  • Indexed Mounting Base with 16 Discrete Positions for Beam Steering
  • Ø1" Optic Mount with 16 Indexed Positions
  • Ball Bearing and V-Groove Design Results in Repeatability Better than 10 µrad
  • Fabricated from Black Anodized Aluminum

These indexing mounts allow a shared laser beam to be redirected within multiple setups or for an optical signal to be interchanged between multiple test instruments. The NX1N(/M) indexing optic mount is designed to hold Ø1" optics no more than 7 mm (0.27") thick, while the NX1NF(/M) indexing mounting base features a top-located 8-32 (M4) tapped hole for general-purpose mounting. Both indexing mounts have three 8-32 (M4) tapped mounting holes on the bottom plate, enabling multiple mounting options, and can be easily positioned at one of 16 discrete positions. In addition, a through hole in the side of the base accepts a 5/64" (2.00 mm) balldriver to attach the mount to a standard Ø1/2" post.

Please Note: The top plate of the NX1N(/M) indexing mount for Ø1" optics is compatible with the bottom plate of the NX1NF(/M) indexing mounting base and the top plate of the NX1NF(/M) indexing mounting base is compatible with the bottom plate of the NX1N(/M) indexing mount for Ø1" optics.

Repeatability Testing

A selection of Thorlabs Kinematic Bases were tested to determine the deviation of a reflected beam attributed to removing and replacing the top plate of the base. The test setup (see photo below and on the left) consisted of an S1FC635 fiber-coupled laser source, terminating in a fiber collimator that was held in a POLARIS-K1 Mirror Mount. The collimated beam was directed towards a BB1-E02 mirror housed in an LMR1 fixed mount that was post mounted on the kinematic base being tested (see photo below and center). After reflecting off the first mirror, the beam traveled towards and reflected off of a second mirror housed in a POLARIS-K1 mount. After reflection, the light was directed onto a PDP90A Lateral Effect Position Sensor that had three SM05L10 SM05-Threaded Lens Tubes attached to the front to block stray light (see photo below and to the right). The total beam path is shown in the first photo and is 1 m long.

Indexing Mounting Base: Ø1.3" (Ø33 mm)

Indexing Mounting Base
Click to Enlarge
Kinematic mounts, such as the KM100, can be mounted to the NX1NF to allow for tip and tilt adjustments.
  • Indexed with 16 Positions at 22.5° Increments
  • Top Plate has an 8-32 (M4) Tap for Component Mounting
  • <10 µrad Repeatability
  • Three 8-32 (M4) Tapped Mounting Holes in Bottom Plate
  • Easy, Repeatable Exchange of Optical Components

The NX1NF(/M) Indexing Base features 16 indexed positions every 22.5° allowing mounted components to be held at both 45° and 90°. The angular positions are engraved on the base plate for fast alignment. The top plate returns to any given position, indicated with an engraved witness line, with a repeatability of better than 10 µrad. This mount is ideal for redirecting a laser to multiple targets on an optical table, as well as for precise switching of shared laser systems.

Top and Bottom Plates of the NX1NF(/M) 

For maximum stability, the center of gravity of components mounted to the top plate, NX1NFT(/M), should be located within the designated mounting region (see photo above).

Neodymium iron magnets couple the top and bottom plates while stainless steel ball bearings and V-grooves provide the 16 indexing positions. Three 8-32 (M4) tapped mounting holes in the bottom plate allow the mount to be secured to a Ø1/2" post. A small through hole, located directly under the 90° engraving on the bottom plate, accepts a 5/64" (2 mm) balldriver to help provide enough torque when attaching the mount to the post. For information about testing done on the repeatability of the NX1NF and other kinematic bases, please see the Repeatability tab.

Please Note: The top plate of this indexing mount is compatible with the bottom plate of the NX1N(/M) 16-position, indexing mount (sold below).

Indexing Mount for Ø1" Optics

Indexing Optic Mount
Click to Enlarge
The NX1N(/M) Indexing Mount can hold an optic at any one of 16 positions, including 45° and 90°.
  • Indexed with 16 Positions at 22.5° Increments
  • Holds Ø1" Optics up to 7 mm (0.27") Thick
  • <10 µrad Repeatability
  • Three 8-32 (M4) Mounting Holes in Bottom Plate
  • Easy, Repeatable Exchange of Optical Components

The NX1N(/M) Indexing Mount for Ø1" optics features 16 indexed positions every 22.5°, allowing the optic to be held at both 45° and 90°. The angular positions are engraved on the base plate for fast alignment. The top plate returns to any given position, indicated with the engraved witness line, with a repeatability of better than 10 µrad. This mount is ideal for redirecting a laser to multiple targets on an optical table.

The included SM1 (1.035"-40) retaining ring (SM1RR) secures the optic against the front lip of the mount. This indexing mount can hold optics that are no greater than 7 mm (0.27") thick. Neodymium iron magnets couple the top and bottom plates, while stainless steel ball bearings and V-grooves provide the 16 indexed positions. Three 8-32 (M4) tapped mounting holes in the bottom plate allow the mount to be secured to a Ø1/2" post. A small through hole, located directly under the 90° engraving on the bottom plate, accepts a 5/64" (2.00 mm) balldriver to help provide enough torque when attaching the mount to the post.

Please Note: The top plate of this indexing mount is compatible with the bottom plate of the NX1NF (NX1NF/M) 16-position, indexing mounting base.
