RSF-25C-568RU 25 mm Dia. Mounted Raman Longpass Edge Filter; t=3.5mm 568.2nm

The RSF-25C-568RU is a 25 mm diameter mounted Raman longpass edge filter, designed and manufactured by OptoSigma. This filter is specifically engineered for applications that require precise wavelength selection and blocking, particularly in the field of Raman spectroscopy.

The filter features a longpass edge at 568.2 nm, meaning it allows transmission of wavelengths longer than 568.2 nm while effectively blocking shorter wavelengths. This characteristic is crucial in Raman spectroscopy, where it helps to minimize fluorescence and enhance the Raman signal.

The filter is constructed with a circular geometry, boasting a diameter of 25 mm and a thickness of 3.5 mm. This robust construction ensures durability and stability, making it suitable for various optical setups. The filter's material ID, UVFS MAL-1965, further attests to its high-quality construction and performance.

The RSF-25C-568RU is coated with OptoSigma's proprietary RSF-568RU coating on both the front and back surfaces. This coating enhances the filter's performance, ensuring optimal transmission and blocking characteristics. The filter's shape is that of a thin lens, further contributing to its versatility and ease of integration into various optical systems.
