Mechanical Dimensions Of Optical Filters

Source: Alluxa, Inc.

When it comes to optical components, understanding the mechanical dimensions of optical filters is crucial to ensure their proper functionality. Clear aperture (CA) is a key parameter that denotes the specific dimensional area within an optical component where precise specifications must be adhered to. Another important parameter is parallelism, which measures the angle between two surfaces of the optical filter.

To ensure accuracy and adherence to specifications, various measurement tools are employed in the evaluation of optical filters. Interferometers, autocollimators, goniometers, and coordinate measurement machines are among the tools utilized by experts to assess the mechanical dimensions of optical filters with high precision and reliability.
