1020FIB25 25 mm Dia. Standard Interference Bandpass Filter 1020nm
The 1020FIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1020nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. This particular model has a cut-on wavelength of 1012.5nm and a cut-off wavelength of 1027.5nm, ensuring a narrow and precise bandwidth for your optical system.
The 1020FIB25 is made from UVFS Mal-1965, a material known for its excellent optical properties. The filter has a thickness of 6.1mm, providing sufficient mechanical strength while maintaining minimal optical thickness.
The front and back surfaces of the filter are coated with KNI 1020DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of your optical system.
The filter is shaped as a Thin Lens, which can be beneficial in certain optical system designs. It is currently in stock and available for immediate purchase through the vendor's website.
