PlaneWave 20 inch Infrared Dall-Kirkham Optical Tube Assembly

The Planewave Infrared Optical Tube 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 lenses, only reflective components to the design. The reflective 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. The IR DK is available in the three different apertures: 20"; 17" and 12.5"
