785-20 NNF-12.5 12.5 mm Dia. Mounted Narrow-Band Notch Filter; t=3mm 785nm

The 785-20 NNF-12.5 is a narrow-band notch filter developed by Iridian Spectral Technologies, a leading vendor in the optical industry. This filter, with a catalog number 785-20 NNF-12.5, is specifically designed for applications that require precise wavelength selection and rejection.

The filter is circular in shape with a diameter of 12.5 mm, making it suitable for a wide range of optical systems. It has a thickness of 3 mm, providing sufficient mechanical strength while maintaining minimal optical path differences. The filter is constructed from UVFS Mal-1965, a material known for its excellent optical properties and durability.

The 785-20 NNF-12.5 filter is coated with IRR 785-20-NNF on both the front and back surfaces. This coating enhances the filter's performance by ensuring high transmission at the desired wavelength and efficient rejection of unwanted wavelengths. The coating also provides excellent environmental stability, ensuring the filter's performance over a wide temperature range and under various humidity conditions.

The filter is designed for a central wavelength (CWL) of 785 nm, making it ideal for applications in laser spectroscopy, bio-imaging, fluorescence detection, and other areas where narrow-band wavelength selection is crucial. The filter is currently in stock and available for immediate shipping, as indicated by its weblink status.
