PlaneWave Infrared Dall-Kirkham Optical Tube Assembly 12.5"

 

This is a Dall-Kirkham optical design with coatings that are optimized to transmit in infrared wavelengths.  It is diffraction limited across a 20mm image circle at the focal plane.  There are no refractive lens, only reflective components to the design.  The reflectives coatings are a protected gold which give better than 98% reflectivity from .65 micron (650nm) to 5 micron (5000nm).  This design is ideal for infrared astronomy or LIDAR applications.
