Spatial Filter Holder / MSF-2

Spatial filters are optical instruments for eliminating distorted laser wavefronts and noise to emit beams in clean spherical waves. Used in optical systems such as interferometers and holograms where wavefront quality is critical.

Part Number
◦Since the objective lens is fitted with a linear motion stage with screw to adjust focal point position, and the pinhole is fitted with a precision two-axis pinhole holder to adjust in-plane position, spot light of the laser will pass the pinhole with good reproducibility.
◦Have an overall tilt adjustment mechanism.
◦A well corrected achromatic in the output beam of the spatial filter can be used to collimate the filtered beam.
