1200DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1200nm
The 1200DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1200nm. 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 1194.5nm and a cut-off wavelength of 1205.5nm, ensuring a narrow and precise bandwidth for your optical system.
The 1200DIB12 is made from UVFS Mal- 1965, a material known for its optical properties and durability. It features a Thin Lens shape, which is beneficial for applications that require minimal optical path deviation. The filter has a thickness of 6.1mm, providing sufficient structural integrity while maintaining a low profile.
The front and back surfaces of the filter are coated with KNI 1200DIB, 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.
