785DIJ25 25 mm Dia. Standard Interference Bandpass Filter 785nm
The 785DIJ25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 785nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. The 785DIJ25 is cut on at 780nm and cut off at 790nm, providing a narrow band of transmission. This makes it ideal for applications that require precise wavelength selection.
The filter is made from UVFS Mal-1965, a material known for its optical properties. It has a circular base shape and a thickness of 6.1mm, which provides sufficient structural integrity for most applications. The coating on both the front and back surfaces of the filter is KNI 785DIJ, which contributes to its excellent performance.
The 785DIJ25 is shaped as a Thin Lens, which can be beneficial in certain optical systems where minimal optical path difference is required. This filter is currently in stock and available for immediate purchase through the vendor's website.
