800FIR50 50 mm Dia. Broadband Interference Bandpass Filter 800nm
The 800FIR50 is a 50 mm diameter Broadband Interference Bandpass Filter, specifically designed for use at the 800nm wavelength. 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 780nm, and the cut-off wavelength is 820nm, making it ideal for applications that require narrow-band transmission around the 800nm region.
The 800FIR50 is made from UVFS Mal-1965, a material known for its excellent optical properties. It has a circular base shape and a thickness of 6.1mm, making it suitable for a wide range of optical systems. The physical data of the filter includes a center wavelength (CWL) of 800nm, which is the central wavelength of the passband.
The filter features a KNI 800DIR coating on both the front and back surfaces. This coating is designed to enhance the performance of the filter, providing improved transmission and blocking characteristics. The filter also has a Thin Lens shape, which means it has been designed to minimize optical aberrations and distortions.
The 800FIR50 is currently in stock and available for purchase. More information about this filter, including pricing and delivery times, can be found on the Knight Optical website.
