32-759 25.4 mm Dia. SCHOTT RG850 Black Longpass Color Glass Filter 850nm

The 32-759 25.4 mm Dia. SCHOTT RG850 Black Longpass Color Glass Filter is a high-quality optical component designed for applications that require longpass filtering at 850nm. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website.

The filter is a Color Glass type, which is known for its ability to selectively transmit or block specific wavelengths of light. In this case, the RG850 filter is designed to allow the transmission of light with wavelengths longer than 850nm while blocking shorter wavelengths. This makes it ideal for applications such as infrared (IR) imaging, night vision, and other scenarios where the detection of longer wavelengths is crucial.

The filter has a base shape of Circular, with a diameter of 25.4mm and a thickness of 3mm. This compact and robust design makes it suitable for use in a wide range of optical systems. The filter is made from a material identified as UVFS MAL-1965, which is known for its excellent optical properties and durability.

The physical data of the filter indicates a cut-on wavelength of 850nm and a cut-off wavelength of 0nm. This means that the filter starts transmitting light at 850nm and continues to transmit all longer wavelengths. The coating on both the front and back surfaces of the filter is EDM 54-664, which is a broadband antireflection coating designed to minimize surface reflections and improve transmission.

The filter's shape is Thin Lens, which suggests that it may have some lens-like properties. However, without additional information, it is difficult to specify these properties.
