RSF-25C-633RU 25 mm Dia. Mounted Raman Longpass Edge Filter; t=3.5mm 632.8nm

The RSF-25C-633RU is a 25 mm diameter mounted Raman longpass edge filter, specifically designed for blocking 632.8nm wavelengths. 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 632.8nm, effectively blocking all wavelengths shorter than this. The cut off, or the point at which the filter starts to block wavelengths, is 0, indicating that it blocks all wavelengths shorter than 632.8nm.

The filter is made from UVFS Mal-1965, a material known for its optical properties. It has a thickness of 3.5mm, providing durability and stability. The filter's geometry is circular, with a diameter of 25mm, making it suitable for a wide range of applications.

The filter's coating is Opt RSF-633RU on both the front and back, providing optimal performance and protection. The shape of the filter is thin lens, which is ideal for applications that require a flat, thin optical element.
