67-891 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=6.9 mm 350nm
The 67-891 is a 50 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for applications requiring a narrow passband, with a central wavelength (CWL) of 350 nm and a full width at half maximum (FWHM) of 10 nm.
The filter is constructed with a UVFS material, identified as MAL-1965, and has a thickness of 6.9 mm. It features a thin lens shape, providing versatility and ease of integration into various optical systems. The cut-on wavelength is 330 nm, and the cut-off wavelength is 370 nm, ensuring a tight control over the spectral range.
The 67-891 is coated with EDM 67-757 on both the front and back surfaces. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall signal-to-noise ratio in the desired passband.
This filter is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its valid weblink status. The provided weblink offers detailed product information, specifications, and purchasing options, making it a valuable resource for those interested in this optical component.
