1700DIB25 25 mm Dia. Standard Interference Bandpass Filter 1700nm
The 1700DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1700nm. 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. The cut-on wavelength is 1692.5nm, and the cut-off wavelength is 1707.5nm, providing a narrow bandwidth for precise optical applications.
The 1700DIB25 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 requiring minimal optical path deviation. The filter has a thickness of 6.1mm, providing sufficient mechanical strength while maintaining minimal impact on the optical path.
The front and back surfaces of the filter are coated with KNI 1700DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by ensuring high transmission within the passband and low reflection at the boundaries.
The filter is currently in stock and can be purchased directly from Knight Optical's website using the provided weblink. The link has been verified and is valid at the time of writing.
