32-758 25.4 mm Dia. SCHOTT RG830 Black Longpass Color Glass Filter 830nm

The 32-758 25.4 mm Dia. SCHOTT RG830 Black Longpass Color Glass Filter is a specialized optical component designed for applications requiring longpass filtering at 830nm. 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 circular component with a diameter of 25.4mm, making it suitable for a wide range of optical systems. It has a thickness of 3mm, providing sufficient structural integrity while minimizing optical distortion. The base shape of the filter is a Thin Lens, which is optimal for applications requiring minimal interference with light paths.

The material of the filter is identified as UVFS MAL-1965, a proprietary material used in optical filters. This material is known for its excellent optical properties, including high transmittance and low absorption across the spectral range of interest.

The RG830 filter is a longpass filter, meaning it allows light of wavelengths greater than 830nm to pass through while blocking shorter wavelengths. This is achieved through a precise coating process, resulting in a cut-on wavelength of 830nm and a cut-off wavelength of 0nm. The coating on both the front and back surfaces of the filter is EDm 54-663, a broadband antireflection coating designed to minimize surface reflections and improve transmission.
