65-157 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 540nm
The 65-157 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 25 mm and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID category, and it is hard coated for enhanced durability.
The filter's primary function is to allow light transmission within a specific range of wavelengths, while blocking other wavelengths. In this case, the Cut-On wavelength is 535 nm, and the Cut-Off wavelength is 545 nm, with a Central Wavelength (CWL) of 540 nm. This makes it ideal for applications that require narrowband transmission around the 540 nm wavelength.
The coating on both the front and back of the filter is EDM 65-096, which is specifically designed to work with this type of filter. The filter's shape is that of a Thin Lens, which is often used in optical systems to reduce weight and thickness.
The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its Valid - in stock status. For more detailed information or to make a purchase, users can follow the provided weblink.
