800DIR25 25 mm Dia. Broadband Interference Bandpass Filter 800nm
The 800DIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed to operate at a central wavelength of 800nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking out unwanted wavelengths. The 800DIR25 is cut on at 780nm and cut off at 820nm, making it ideal for applications that require narrow-band light in the 800nm region.
The filter is made from UVFS Mal- 1965, a material known for its optical properties in the ultraviolet, visible, and shortwave infrared regions. The filter has a thickness of 6.1mm, providing sufficient structural integrity for most applications.
The 800DIR25 features a Thin Lens shape, which is beneficial for applications that require minimal optical path deviation. The filter's front and back are coated with KNI 800DIR, a coating specifically designed to enhance the filter's performance at 800nm.
According to the vendor, the 800DIR25 is currently in stock and available for immediate purchase. For more information, users are encouraged to visit the vendor's website using the provided weblink.
