740DIB25 25 mm Dia. Standard Interference Bandpass Filter 740nm
The 740DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 740nm. 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 735nm, and the cut-off wavelength is 745nm, making it highly effective in isolating the 740nm wavelength.
The filter is made from UVFS Mal-1965, a material known for its optical properties and durability. It has a circular base shape, a common standard in optical filters due to its ease of integration into various systems.
The physical data of the filter includes a thickness of 6.1mm, which is crucial for determining the filter's placement and alignment in an optical system. The coating on both the front and back surfaces of the filter is KNI 740DIB, a proprietary coating developed by Knight Optical for enhanced performance.
The filter's shape is classified as a Thin Lens, indicating its potential use in lens systems where minimal thickness is required. The filter is currently in stock and available for immediate purchase through the vendor's website.
