1220DIB25 25 mm Dia. Standard Interference Bandpass Filter 1220nm
The 1220DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1220nm. 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 1214.5nm and a cut-off wavelength of 1225.5nm, ensuring a narrow and precise bandwidth for your optical system.
The 1220DIB25 is made from UVFS Mal-1965, a material known for its excellent optical properties. It features a Thin Lens shape, which is beneficial for applications where space is a constraint. The filter has a thickness of 6.1mm, providing sufficient structural integrity while minimizing unnecessary bulk.
The front and back surfaces of the filter are coated with KNI 1220DIB, 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 currently in stock and available for immediate purchase through the vendor's website. For more information, please refer to the provided weblink.
