65-744 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 550nm
The 65-744 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 7.5 mm, specifically designed for a central wavelength of 550nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase directly from their website.
The filter is a bandpass type, which means it allows a specific range of wavelengths to pass through while blocking others. In this case, the cut-on wavelength is 510nm, and the cut-off wavelength is 590nm, providing an 80nm full width at half maximum (FWHM). This makes it ideal for applications that require narrow-band filtering around the 550nm wavelength.
The 65-744 filter features a circular shape and is made from UVFS Mal-1965 material. It is coated on both the front and back surfaces with EDM 65-735, ensuring optimal performance and durability. The filter's thin lens shape further enhances its functionality and compatibility with various optical systems.
