750DIB25 25 mm Dia. Standard Interference Bandpass Filter 750nm
The 750DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 750nm. 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 745nm, and the cut-off wavelength is 755nm, making it highly efficient in isolating the 750nm wavelength.
The 750DIB25 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 750nm, ensuring precise wavelength selection. The coating on both the front and back surfaces is KNI 750DIB, a proprietary coating developed by Knight Optical for high-performance bandpass filters.
The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, making it suitable for various optical systems. According to the vendor, the filter is currently in stock and the web link provided leads to its product page for further information.
