67-874 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 250nm

The 67-874 is a 50 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for applications that require precise wavelength selection within the ultraviolet spectrum.

The filter's primary function is to transmit light within a specific range, while blocking other wavelengths. The 67-874 is designed to transmit light at a central wavelength (CWL) of 250nm, with a full width at half maximum (FWHM) of 10nm. This means it allows light transmission between 245nm and 255nm, making it ideal for applications that require narrow-band ultraviolet light.

The filter is constructed with a thickness of 3.5mm, providing durability and stability. It features a traditional coating on both the front and back surfaces, identified as EDM 67-740. This coating enhances the filter's performance and longevity, ensuring optimal functionality in various environments.
