Melles Griot General Description:
This laser collimator will provide a highly collimated output beam when used in conjunction with the Melles Griot spatial filter. Divergence of the collimated beam is inversely proportional to the beam diameter. When the output aperture is filled, the output beam divergence from the 50mm collimator is only 0.015 milliradians.
These three-element Collimators are diffraction limited in their performance. Wavefront distortion is less than 1/8 wave over the entire aperture. They are designed to provide excellent performance at 488nm and 514nm, as well as 633nm. All air/glass surfaces are coated with our HEBBARTM high-efficiency, broadband and antireflection coating for high transmission.
Focus is adjustable from 2 meters to infinity with the large knurled control ring on the front of the housing. The rear of the collimator attaches directly to a spatial filter (09 LSF 001) using a standard 1 inch-32 TPI threaded boss. Collimators are mounted in black anodized aluminum housings.
