960DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 960nm
The 960DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 960nm. 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. In this case, the cut-on wavelength is 955nm, and the cut-off wavelength is 965nm, making it highly effective in isolating the desired wavelength.
The 960DIB12 is made from UVFS Mal- 1965, a material known for its optical properties and durability. It features a Thin Lens shape, which is beneficial for applications that require minimal optical path deviation.
The filter's physical data includes a center wavelength of 960nm, which is the average of the cut-on and cut-off wavelengths. This wavelength is crucial in applications such as laser systems, spectroscopy, and optical imaging.
The coating on both the front and back of the filter is KNI 960DIB. This coating enhances the filter's performance by ensuring high transmission at the desired wavelength and low transmission outside of it.
