14-762 12.5 mm Dia. OD 6.0 Ultra-Thin Notch Filter 658nm

The 14-762 12.5 mm Dia. OD 6.0 Ultra-Thin Notch Filter, offered by Edmund Optics, is a specialized optical component designed to transmit light within a specific wavelength range while blocking light at other wavelengths. This notch filter is specifically tuned to 658nm, making it ideal for applications that require narrowband wavelength selection.

The filter has a circular geometry with a diameter of 12.5mm and a thickness of 0.3mm, classifying it as an ultra-thin optical element. This thin design not only reduces its overall weight but also minimizes optical path differences, making it suitable for applications that require high precision and accuracy.

The filter's material ID is UVFS MAL-1965, a detail that can be crucial for designers and engineers when considering the filter's compatibility with other optical elements in their system. The filter's coating, both on the front and back surfaces, is identified as EDM 14-762, suggesting a specific anti-reflective or protective coating that enhances the filter's performance and durability.

The filter's physical data includes a center wavelength (CWL) of 658nm, aligning with its notch wavelength. This CWL is a critical parameter in determining the filter's transmission characteristics.
