880DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 880nm
The 880DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 880nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 875nm, and the cut-off wavelength is 885nm, providing a narrow bandwidth for optimal performance.
The 880DIB12 is made from UVFS Mal-1965, a material known for its excellent optical properties. The filter has a Thin Lens shape, which is beneficial for applications requiring minimal optical path deviation.
The front and back surfaces of the filter are coated with KNI 880DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflection and increasing transmission within the passband.
The filter has a thickness of 6.1mm, providing robustness and durability. It is currently in stock and available for immediate purchase through the vendor's website. The weblink provided leads directly to the product page for convenient access.
