FR-RG850 12.7 mm Dia. Colored Glass Absorptive Longpass Filter 850nm

The FR-RG850 is a Longpass Filter, specifically designed for use in optical systems that require infrared light absorption. Sourced from the reputable vendor MKS/Newport, this filter boasts a catalog number of FR-RG850 and is readily available for purchase.

This circular filter has a diameter of 12.7 mm and a thickness of 3 mm, making it a suitable choice for applications that require a compact yet robust optical component. The filter is constructed from UVFS Mal-1965, a material known for its excellent optical properties.

The FR-RG850 features a cut-on wavelength of 850 nm, meaning it begins to transmit light at this wavelength and above. The cut-off wavelength is 0 nm, indicating that it blocks all wavelengths below 850 nm. This makes it ideal for applications that require the absorption of shorter wavelengths and the transmission of longer wavelengths.

The filter is coated with New RG850 on both the front and back surfaces, enhancing its performance and durability. Its thin lens shape further contributes to its versatility, making it a valuable addition to any optical system.
