The 86-660 is a Bandpass Filter with a diameter of 25 mm, sourced from Edmund Optics. This filter is designed to transmit light within a specific range of wavelengths, centered around 800nm, while blocking other wavelengths. The cut-on wavelength is 787.5nm, and the cut-off wavelength is 812.5nm, providing a narrow bandwidth of 25nm.
This filter is made from UVFS Mal-1965 material and has a thickness of 3.5mm. It features hard coating on both the front and back surfaces, indicated by the coating codes "edm 86-648" for the front and the same code for the back. The filter's shape is defined as a Thin Lens, and it is available for purchase directly from the vendor's website, where it is currently in stock.
The 86-660 is a part of Edmund Optics' extensive catalog, which includes a wide variety of optical elements. As a Bandpass Filter, it is particularly useful in applications where a narrow range of wavelengths needs to be isolated, such as in fluorescence microscopy, spectroscopy, and other optical analysis techniques.
