RSF-25C-785RU 25 mm Dia. Mounted Raman Longpass Edge Filter; t=3.5mm 785nm

The RSF-25C-785RU is a 25 mm diameter mounted Raman longpass edge filter, specifically designed for applications involving the 785 nm 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 while blocking or reflecting shorter wavelengths. The cut-on wavelength for this filter is 785 nm, ensuring that only wavelengths greater than this value will pass through. The cut-off wavelength is 0 nm, indicating that all wavelengths shorter than 785 nm will be blocked.

The filter is made from UVFS-MAL 1965, a material specifically chosen for its optical properties. It has a circular base shape, a common choice for its ease of integration into various optical systems. The filter's thickness is 3.5 mm, providing sufficient structural integrity while minimizing optical distortions.

The front and back of the filter are coated with Opt RSF-785RU, a specialized coating that enhances the filter's performance at the 785 nm wavelength. The filter's shape is that of a thin lens, further enhancing its optical properties and making it suitable for a wide range of applications.

According to the vendor's information, this filter is currently in stock and can be readily purchased. The filter's webpage provides more detailed specifications and purchasing information.
