850DIR25 25 mm Dia. Broadband Interference Bandpass Filter 850nm
The 850DIR25 is a 25 mm diameter Broadband Interference Bandpass Filter, specifically designed for the wavelength of 850nm. This filter is sourced from Knight Optical, a renowned 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 other wavelengths. In this case, the cut-on wavelength is 830nm, and the cut-off wavelength is 870nm, making it ideal for applications that require narrow-band light transmission around the 850nm wavelength.
The 850DIR25 features a circular base shape and is made from UVFS Mal- 1965 material. It has a thickness of 6.1mm, and its physical data includes a center wavelength (CWL) of 850nm. The filter is coated with KNI 850DIR on both the front and back, ensuring optimal performance and durability.
The filter's geometry is defined by its 25mm diameter, making it suitable for various applications that require a broadband interference bandpass filter of this size. The shape of the filter is thin lens, which is beneficial for applications that require minimal added thickness or weight.
The filter is currently in stock and available for immediate purchase. For more information, you can visit the following link: https://www.knightoptical.com/stock/default/catalog/product/view/id/1007/s/850nm-interference-bandpass-filter-25mmdiax40nmbw/category/73/
