The 64-650 is a 25 mm diameter Shortpass Filter, designed and manufactured by Edmund Optics. This filter features a thickness of 3mm and is constructed using UVFS material, identified as Mal-1965. The Shortpass Filter is specifically designed to transmit light below a certain wavelength while blocking light above that wavelength. In this case, the cut-on wavelength is 0 nm, and the cut-off wavelength is 975 nm.
The filter's coating is a crucial component, enhancing its functionality. Both the front and back of the filter are coated with the EDM 64-650 coating, which is specifically designed for this filter. The filter's shape is that of a Thin Lens, optimized for minimal distortion and maximum light transmission.
