The 86-685 is a Dichroic Shortpass Filter, measuring 12.5 x 17.6 mm with a thickness of 1.05mm, manufactured by Edmund Optics. This filter is designed to reflect shorter wavelengths and transmit longer wavelengths, making it ideal for applications that require the separation of light based on wavelength.
The filter's cut-on wavelength is 0 nm, indicating that it reflects all wavelengths shorter than its cut-off wavelength of 1100 nm. This makes it suitable for use in applications where the removal of infrared light is necessary. The filter's coating, both on the front and back, is EDM 86-679, which is a dichroic coating designed for high reflectivity in the visible range and high transmissivity in the infrared range.
The filter is rectangular in shape and has a base shape of a thin lens. It is made from UVFS Mal-1965, a material known for its excellent optical properties and durability. The filter is currently in stock and available for purchase on the Edmund Optics website, as indicated by its weblink status.
