The 66-070 50.8 x 50.8 mm Hoya IR-80 Black Longpass Color Glass Filter is a specialized optical component designed for applications involving infrared light. Sourced from Edmund Optics, this filter has a catalog number of 66-070 and is currently in stock, as indicated by its weblink status.
This filter is of the type 'Color Glass' and features a rectangular base shape. It is made from a material identified as 'uvfs mal- 1965'. The filter's primary function is to allow light at wavelengths of 800nm and above to pass through while blocking lighter wavelengths. This is achieved through a cut-on wavelength of 800nm and a cut-off wavelength of 0nm.
The filter has a thickness of 2.5mm and its geometry measures 50.8mm in width and 50.8mm in height. The coating on both the front and back of the filter is 'edm 66-048', which contributes to its optical properties. The filter's shape is described as 'Thin Lens', indicating its potential use in lens systems.
