67-785 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 850nm

The 67-785 is a mounted traditional coated bandpass interference filter, specifically designed for applications requiring a narrow passband. This filter, offered by Edmund Optics, is characterized by a center wavelength of 850nm and a full-width half-maximum (FWHM) of 10nm.

The filter has a circular geometry with a diameter of 12.5mm, ensuring a wide field of view for various optical systems. It boasts a thickness of 5.9mm, providing robustness and stability during integration into optical assemblies. The filter's material ID, UVFS MAL-1965, indicates its composition, which is crucial for understanding its optical properties and compatibility with other components.

The 67-785 filter features a cut-on wavelength of 845nm and a cut-off wavelength of 855nm, providing a sharp transition between the passband and the blocked wavelengths. This characteristic is essential for applications requiring high contrast and minimal stray light. The coating on both the front and back surfaces of the filter is EDMD 67-785, which enhances its performance by reducing reflection and increasing transmission.

The filter's shape is that of a thin lens, suggesting its potential use as a standalone optical element or as part of a more complex optical system. The catalog number, 67-785, is a unique identifier that allows for easy tracking and ordering of this specific filter. The vendor, Edmund Optics, is a reputable supplier of optical components, ensuring the filter's quality and reliability.
