65-676 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 394nm

The 65-676 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in applications where precise wavelength selection is critical. The filter features a center wavelength of 394 nm and a full width at half maximum (FWHM) of 10 nm, making it ideal for use in systems that require narrowband spectral filtering.

The filter is constructed with a base shape of a circle, and it has a thickness of 7.5 mm. The material used in its construction is UVFS Mal-1965, a material specifically chosen for its optical properties and durability. The filter is coated on both the front and back surfaces with EDM 65-616, a proprietary coating developed by Edmund Optics to enhance the filter's performance and longevity.

The physical data of the filter includes a cut-on wavelength of 389 nm and a cut-off wavelength of 399 nm. This means that the filter begins to transmit light at 389 nm and stops transmitting at 399 nm, effectively filtering out any wavelengths outside of this range. The cut-on and cut-off wavelengths are crucial specifications in determining the filter's ability to isolate specific wavelengths.

The filter is designed in the shape of a thin lens, allowing it to be easily integrated into various optical systems. It is currently in stock and available for immediate purchase, as indicated by its weblink status. The filter's catalog number is 65-676, and more information about it can be found on the Edmund Optics website.
