67-879 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 270nm
The 67-879 is a 50 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 3.5 mm and a central wavelength of 270 nm. This filter, offered by Edmund Optics, is designed to transmit light within a specific range of wavelengths while blocking other wavelengths, making it ideal for applications that require narrowband light transmission.
The filter's geometry includes a 50 mm diameter, providing a large surface area for light transmission, and a thickness of 3.5 mm, ensuring durability and stability. The physical data of the filter indicates a cut-on wavelength of 265 nm and a cut-off wavelength of 275 nm, with a center wavelength of 270 nm. This means the filter allows light transmission between 265 nm and 275 nm, with the highest transmission at 270 nm.
The 67-879 filter features a UVFS MAL-1965 material ID, which is known for its excellent optical properties in the ultraviolet region. The filter is coated on both the front and back surfaces with EDM 67-745, a proprietary coating developed by Edmund Optics for enhanced performance and durability.
The filter's shape is that of a thin lens, which minimizes optical aberrations and ensures efficient light transmission. The catalog number for this item is 67-879, and it is currently in stock on the Edmund Optics website, as indicated by its weblink status.
