Optical/Mirror Mounts

Optical/Mirror Mounts

Low cost, high quality mirror mounts of different sizes, accuracy, shapes and adjustment ranges.

Beam Expander Mount

The beam expander mounts are used to hold a beam expander, red pilot diode, mirrors with the screw M22x0.75mm. They are 4D adjustable for optics alignment at angles, positions.

beam expander mount

  • Model: BEM-22x0.75
  • 4D adjustable (4-axis adjustable) (X and Y directions travel ±2mm, X and Z directions tilting ±4 deg)
  • Suitable for the beam expander with a screw of M22x0.75mm
  • Dimension: 60x60x45mm

Custom-made beam expander mounts available upon request.

STAL Series Mirror Mounts

1. STAL-4LL Series Four-Axis Optical Mount

STAL-4LL-OM Four-Axis Optical Mount is a precise and robust solution for mounting telescopes, beam expanders, beam shapers, or any other heavy optics.

It allows to optics adjustment in 4 degrees of freedom:

  • Two axes of angular adjustment can be tilted in a range up to ±4 degrees which are realized by two screws of thread pitch 250 μm (100TPI).
  • Two axes of lateral adjustment can be moved within ±2 mm and are driven by two screws of thread pitch 200 μm. Both – translation and rotation positions can be locked which secures long-term stability for heavy optics which is STAL-4LL-OM core advantage over spring-based positioners.

Features

  • Two-axis kinematic mount with two screws (thread pitch 250 μm (100TPI)) with position lock. Adjustment range up to ±4 degrees
  • Two-axis translation stage with ±2 mm travel range driven by two screws (thread pitch 200 μm). Translation stage with position lock
  • 5 mounting holes (M4) for convenient mount positioning

We can customize this product to your needs.

2. STAL-SD Series Industrial Optical Mounts

The STAL-SD industrial precisely adjustable mirror mount provides excellent performance for demanding applications. The design ensures stress-free low distortion mounting for optics, excellent holding force and pointing stability. Type SD mount allows precise mirror adjustment in both X and Y directions. 100TPI micro screws provide accurate adjustment and easily accessible fully integrated locking mechanism ensuring excellent angle stability. Depending on the application, optics can be held either by specially designed ZeroDef flexure ring or by semi-permanent optical adhesives. The mount is precisely machined from special alloys to provide optimum beam pointing stability over changing environmental conditions such as temperature and transportation shock as well as vibrations and humidity.
