636DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 636nm
The 636DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 636nm. 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 631nm, and the cut-off wavelength is 641nm, making it highly effective in isolating the 636nm wavelength.
The 636DIB12 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 that require minimal optical path deviation.
The filter's physical data includes a center wavelength (CWL) of 636nm, which is the average of the cut-on and cut-off wavelengths. This CWL is crucial in applications that require precise wavelength control.
The front and back of the filter are coated with KNI 636DIB, a coating specifically designed to enhance the filter's performance. This coating ensures high transmission efficiency and excellent wavelength selectivity.
