1220FIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1220nm
The 1220FIB12 is a 12.5 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 1220FIB12 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's geometry includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for a wide range of optical setups.
The filter's coating is another crucial aspect. Both the front and back surfaces of the 1220FIB12 are coated with KNI 1220DIB, a coating specifically designed to enhance the filter's performance and durability.
This filter is currently in stock and available for immediate purchase. For more information, you can visit the product page at https://www.knightoptical.com/stock/default/catalog/product/view/id/223/s/1220nm-interference-bandpass-filter-12-5mmdiax11nmbw/category/72/.
