The 65-215 is a Bandpass Filter, specifically designed with a 50 mm diameter and a thickness of 3.5 mm. This filter, offered by Edmund Optics, is a crucial component for applications requiring precise wavelength selection.
The filter's primary function is to allow light within a specific range of wavelengths to pass through while blocking out other wavelengths. The 65-215 is designed to pass light with a central wavelength (CWL) of 520 nm, making it ideal for applications that require the use of green light.
The filter's cut-on wavelength is 515 nm, and the cut-off wavelength is 525 nm. This 10 nm bandpass ensures a high level of transmission for the desired wavelength while effectively blocking out unwanted light. The filter's coating, both on the front and back, is EDM 65-093, which contributes to its high performance.
The 65-215 is shaped as a Thin Lens, a feature that can be beneficial in certain optical systems. It is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
