67-867 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=3.5 mm 200nm

The 67-867 is a 50 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for applications that demand high-performance optical components, with a center wavelength of 200nm and a full-width half-maximum (FWHM) of 10nm.

The filter is constructed with a base shape of a circle, ensuring uniformity and consistency in its optical properties. It boasts a thickness of 3.5mm, providing robustness and durability while maintaining excellent optical quality. The material ID for this filter is UVFS MAL-1965, indicating its specific material composition and manufacturing process.

The 67-867 features a cut-on wavelength of 195nm and a cut-off wavelength of 205nm, ensuring precise control over the spectral range it transmits. The central wavelength of 200nm is where the filter exhibits its highest transmittance, making it ideal for applications that require narrow-band light filtering.

The filter is coated on both the front and back surfaces with EDM 67-733, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and increasing transmission, thereby improving the overall signal-to-noise ratio in the system.

The filter's shape is defined as a thin lens, suggesting its potential use in applications where a lens-like optical component is required. This could include imaging systems, spectroscopy, or any application where precise control over light is necessary.
