632.8-16 NNF-12.5 12.5 mm Dia. Mounted Narrow-Band Notch Filter; t=3mm 632.8nm
The 632.8-16 NNF-12.5 is a Notch Filter, a type of optical element designed to transmit light in a narrow band while blocking light in wider bands on either side of the transmission band. This specific model, sourced from Iridian Spectral Technologies, has a catalog number of 632.8-16 NNF-12.5 and is available for purchase directly from their website.
The filter is circular in shape with a diameter of 12.5 mm and a thickness of 3 mm. It is made from a material identified as UVFS MAL-1965, and its central wavelength (CWL) is 632.8 nm. The coating on both the front and back surfaces of the filter is 'irr 632 8-16-nnf'.
The 632.8-16 NNF-12.5 is designed to be used as a Thin Lens, a type of lens with a very small focal length compared to its diameter. This makes it ideal for use in applications where a wide field of view and minimal distortion are required.
