Filter wheel
High-quality custom and standard filters in a filter wheel are manufactured to match the response of any detector sensitivity spectrum from near-ultraviolet to near-infrared. The computer-controlled device enables automated selection of filters with u¥to 2-in. diameters. The device matches the spectral response curve of detectors for precise photometric, photopic tristimulus (human eye), and astronomical standards.
