65-720 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 694nm

The 65-720 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its 25 mm diameter and 7.5 mm thickness, making it a robust and stable option for various optical applications.

The filter's primary function is to allow light transmission within a specific wavelength range, while blocking out unwanted wavelengths. In this case, the 65-720 is designed to transmit light at a central wavelength (CWL) of 694nm, with a full width at half maximum (FWHM) of 10nm. This makes it ideal for applications that require precise wavelength selection around the 694nm range.

The filter's cut-on wavelength is 689nm, and the cut-off wavelength is 699nm. This means that it begins to transmit light at 689nm and stops transmitting at 699nm, effectively filtering out any wavelengths outside this range.

The 65-720 features a thin lens shape and is coated with EDM 65-660 on both the front and back surfaces. This coating enhances the filter's performance and durability, providing improved resistance to environmental factors and ensuring reliable, consistent performance.
