RSF-25C-647RU 25 mm Dia. Mounted Raman Longpass Edge Filter; t=3.5mm 647.1nm

The RSF-25C-647RU is a 25 mm diameter mounted Raman longpass edge filter, specifically designed for applications requiring a 647.1 nm cut-off wavelength. This precision optical component is sourced from OptoSigma, a renowned vendor known for their high-quality optical elements.

The filter is of the longpass type, which means it allows transmission of longer wavelengths and blocks shorter ones. In this case, it has a cut-off wavelength of 647.1 nm, ensuring that all wavelengths shorter than this are effectively blocked. This feature makes it ideal for applications where selective wavelength transmission is crucial.

The filter is made from UVFS material, identified as MAL-1965 in the item data. This material is known for its excellent optical properties, making it suitable for a wide range of applications. The filter has a thickness of 3.5 mm, providing sufficient structural integrity while maintaining minimal optical distortion.

The RSF-25C-647RU features a circular geometry, a common shape for optical filters due to its ease of integration into various optical systems. The front and back surfaces of the filter are coated with Opt RSF-647RU, a coating specifically designed to enhance the filter's performance.

The filter's shape is thin lens, suggesting that it may have some light-bending properties. However, without additional information, it's impossible to provide specific details about these properties.
