RSF-25C-808RU 25 mm Dia. Mounted Raman Longpass Edge Filter; t=3.5mm 808nm

The RSF-25C-808RU is a 25 mm diameter mounted Raman longpass edge filter, specifically designed for blocking the 808nm wavelength. This high-quality filter is sourced from OptoSigma, a renowned vendor known for its extensive catalog of 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 is designed to cut on at 808nm, effectively blocking all wavelengths shorter than this. The cut off is 0, indicating that no wavelengths shorter than 808nm will be transmitted.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It has a base shape of a circle, a common choice for filters due to its uniformity and ease of integration into various optical systems.

The RSF-25C-808RU has a thickness of 3.5mm, providing sufficient structural integrity for handling and mounting. The front and back of the filter are coated with Opt RSF-808RU, a coating that enhances the filter's performance and durability.

The filter's geometry is that of a thin lens, suggesting that it may have some focusing or diverging properties. However, this is not explicitly stated in the provided data, so it remains an assumption.
