67-764 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9 mm 440nm
The 67-764 is a 12.5 mm diameter, mounted traditional coated bandpass interference filter with a thickness of 5.9 mm, specifically designed for a central wavelength of 440nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock with a valid weblink for easy access to additional information.
As a bandpass filter, the 67-764 allows light to pass through a specific range of wavelengths while blocking out other wavelengths. This particular filter is designed with a cut-on wavelength of 435nm and a cut-off wavelength of 445nm, making it ideal for applications that require the precise filtering of light in the blue spectrum.
The filter is made from UVFS MAL-1965 material, a common choice for optical filters due to its excellent optical properties. It features a thin lens shape and is coated on both the front and back surfaces with the EDM 67-764 coating. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission in the desired wavelength range.
