36-334 12.5 x 12.5 mm OD 3.0 Ultra-Thin Notch Filter 785nm

The 36-334 12.5 x 12.5 mm OD 3.0 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 785nm, making it ideal for applications that require narrowband filtering around this wavelength.

The filter is rectangular in shape, with a width and height of 12.5mm each, and a thickness of 0.3mm, making it ultra-thin and suitable for applications where space is a constraint. The base material of the filter is UVFS Mal-1965, a common material used in optical filters due to its excellent optical properties.

The filter's coating is another crucial aspect. Both the front and back surfaces of the filter are coated with EDM 36-398, a coating specifically designed to enhance the filter's performance. This coating helps to ensure high transmission at the desired wavelength and low transmission at other wavelengths, thereby improving the filter's notch characteristics.

The physical data of the filter includes a center wavelength (CWL) of 785nm, further emphasizing its notch filter capabilities. The filter's shape is that of a thin lens, which not only aids in its functionality but also contributes to its thin profile.
