970DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 970nm
The 970DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 970nm. This filter is sourced from Knight Optical, a renowned vendor known for their high-quality optical elements.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 965nm, and the cut-off wavelength is 975nm, making it highly effective in isolating the desired wavelength.
The 970DIB12 is made from UVFS Mal- 1965, a material specifically chosen for its optical properties. It has a thickness of 6.1mm, providing sufficient structural integrity while minimizing optical distortions.
The filter features a Thin Lens shape, which is beneficial in applications where space is a constraint. The front and back of the filter are coated with KNI 970DIB, a proprietary coating developed by Knight Optical to enhance the filter's performance and durability.
This filter is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
