1100DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1100nm
The 1100DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1100nm. 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 1091.75nm and a cut-off wavelength of 1108.25nm, ensuring a narrow and precise bandwidth for your optical system.
The 1100DIB12 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 minimal thickness is required. 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 notable feature. Both the front and back surfaces are coated with KNI 1100DIB, a coating specifically designed to enhance the filter's performance at the 1100nm wavelength. This coating ensures high transmission within the passband and low reflection at the filter's surfaces.
