65-674 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 340nm
The 65-674 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 7.5 mm, specifically designed for use at a central wavelength of 340nm. This filter is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock with a valid web link provided for easy accessibility and purchase.
The filter is a bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. This particular model has a cut-on wavelength of 335nm and a cut-off wavelength of 345nm, making it ideal for applications that require narrow-band light transmission around the 340nm range.
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, which is beneficial for applications where space is a constraint. The front and back of the filter are coated with EDM 65-614, a proprietary coating from Edmund Optics that enhances the filter's performance and durability.
