The RSF-25C-532RU is a 25 mm diameter mounted Raman longpass edge filter, specifically designed for blocking the 532nm wavelength. This filter is sourced from OptoSigma, a renowned vendor known for its high-quality optical elements.
The filter is of the longpass type, which means it allows transmission of longer wavelengths and blocks shorter wavelengths. In this case, it is designed to cut on at 532nm, effectively blocking all wavelengths below this point. The cut off is 0, indicating that no wavelengths shorter than 532nm will be transmitted.
The filter is made from UVFS MAL-1965 material, a common choice for optical filters due to its excellent transmission properties and durability. The filter has a thickness of 3.5mm, providing a good balance between robustness and light transmission.
The RSF-25C-532RU features a circular shape, a standard in optical filters due to its symmetry and ease of integration into optical systems. The front and back of the filter are coated with Opt RSF-532RU, a proprietary coating developed by OptoSigma to enhance the filter's performance and durability.
The filter is shaped as a thin lens, suggesting that it may have some focusing or collimating properties. However, this is not explicitly stated in the provided data, so it should be confirmed with the vendor.
