2000DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 2000nm

The 2000DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 2000nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. The cut-on wavelength is 1991.5nm, and the cut-off wavelength is 2008.5nm, making it highly effective in isolating the desired wavelength range.

The 2000DIB12 filter is made from UVFS Mal-1965, a material known for its excellent optical properties. The filter has a thickness of 6.1mm, providing sufficient structural integrity for most applications.

The front and back surfaces of the filter are coated with KNI 2000DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflection and increasing transmission within the passband.

The filter is shaped as a Thin Lens, which can be beneficial in certain optical systems where a lens-like element is required. The lens shape does not affect the filter's spectral performance but can influence the overall system's optical design.
