The RSF-25C-1064RU is a 25 mm diameter mounted Raman longpass edge filter, specifically designed to block the 1064nm 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 ones. In this case, it is designed to cut on at 1064nm, effectively blocking all wavelengths shorter than this. The cut off is 0, indicating that no wavelengths shorter than 1064nm 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 robustness and stability.
The RSF-25C-1064RU features a circular shape, a standard in optical filters due to its symmetry and ease of integration into various optical systems. The front and back of the filter are coated with Opt RSF-1064RU, 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 light-focusing properties. However, the specific optical properties of the filter, such as its focal length and numerical aperture, are not provided in the item data.
