66-059 25.4 mm Dia. Hoya IR-80 Black Longpass Color Glass Filter 800nm

The 66-059 25.4 mm Dia. 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 is a part of their extensive catalog, boasting a catalog number of 66-059.

This filter is a Longpass type, characterized by its ability to transmit light with wavelengths longer than a specified value, while blocking shorter wavelengths. In this case, the cut-on wavelength is 800nm, meaning it allows the transmission of infrared light with wavelengths longer than 800nm. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths of light shorter than 800nm.

The filter is circular in shape, with a diameter of 25.4mm and a thickness of 2.5mm, making it compatible with a wide range of optical systems. It is made from UVFS Mal-1965, a material known for its optical properties in the infrared spectrum.

The coating on both the front and back of the filter is EDM 66-048, which is likely a proprietary coating developed by Edmund Optics for specific performance characteristics. The filter's shape is described as a Thin Lens, suggesting a precise design for minimal optical aberrations.
