Spatial Filters

The spatial filter is perfect for generating a "clean" coherent light. The input side involves a Z-translator stage that can hold a diffraction-limited aspheric lens to focus the laser throughout a pinhole. For simple modification, the pinhole needs to be positioned in the XY translator stage. Threaded holes on the output part are available for mounting as well as centering. 
Make sure you check the "More details" bottom for choosing the right optics in addition to pinhole for your optical needs.
