1180FIB12 12.5 mm Dia. Standard Interference Bandpass Filter 1180nm
The 1180FIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1180nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
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. The cut-on wavelength is 1174.5nm, and the cut-off wavelength is 1185.5nm, providing a narrow bandwidth for precise optical applications.
The 1180FIB12 filter is made from UVFS Mal- 1965, a material known for its optical properties. It has a thickness of 6.1mm, providing sufficient structural integrity for most applications. The filter's coating, KNI 1180DIB, is applied to both the front and back surfaces, enhancing its performance and durability.
The filter's geometry is that of a Thin Lens, which can be beneficial in certain optical systems where minimal optical path difference is required. The filter's diameter is 12.5mm, making it suitable for use in systems with similar aperture sizes.
