The 36-333 12.5 x 12.5 mm OD 3.0 Ultra-Thin Notch Filter, available from 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 633nm, making it ideal for applications that require the selective filtering of red light.
The filter is rectangular in shape, with dimensions of 12.5 x 12.5 mm, and has a thickness of 0.3mm, making it ultra-thin and suitable for applications where space is a constraint. The filter is constructed from UVFS Mal-1965, a material known for its optical properties.
The filter's coating is another crucial aspect of its design. Both the front and back surfaces of the filter are coated with EDM 36-397, a coating that enhances the filter's performance by ensuring precise wavelength selectivity and high transmission efficiency.
This notch filter is available in a Thin Lens shape, which is a flat, circular shape often used in optical systems. The filter's physical data includes a center wavelength (CWL) of 633nm, further emphasizing its specificity for red light applications.
