65-657 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 671nm

The 65-657 is a Bandpass Filter, specifically designed with a circular base shape and a diameter of 12.5 mm. This filter is sourced from the reputable vendor, Edmund Optics, and boasts a thickness of 7.5 mm. The filter's primary function is to allow light in a specific range of wavelengths to pass through while blocking other wavelengths.

The 65-657 is made from UVFS MAL-1965 material, a choice that enhances its performance and durability. It is designed to operate at a central wavelength (CWL) of 671 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows a narrow band of wavelengths around 671 nm to pass through while blocking out other wavelengths.

The filter's physical data includes a cut-on wavelength of 666 nm and a cut-off wavelength of 676 nm. This indicates the range of wavelengths that the filter begins to transmit and the point at which it stops transmitting, respectively.

The 65-657 features a thin lens shape and is coated on both the front and back with EDm 65-657. This coating enhances the filter's performance and durability, making it an ideal choice for various applications.
