In the field of precision optics manufacturing, large-aperture optical profilers transform the "invisible" micro-geometric world of optical components into a "visible" and definable digital map. They serve not only as the final stage of quality control but, more importantly, as a guiding force throughout the entire manufacturing process. They are the performance cornerstone that drives the continuous breakthrough of advanced optical technologies.

1.Surface Form Control and Guidance for Machining

in the Manufacturing Process this is the most critical application. During the grinding, polishing, and figuring stages of a component, the optical profiler provides essential feedback data.

2. Inspection of Complex Optical Surface Shapes

Precision optics manufacturing has moved far beyond simple spherical surfaces. Optical profilers are a key tool for inspecting these complex forms, such as parabolic and ellipsoidal surfaces. They are capable of directly measuring their deviation from the design form and are one of the few metrology solutions that can provide full-field, high-precision three-dimensional topography.

3. Surface Quality and Roughness Evaluation

Beyond macroscopic form, optical profilers are also used to assess mid-spatial-frequency and low-spatial-frequency surface characteristics. Through measurement, they determine whether the polishing process has introduced scratches, digs, or mid-spatial-frequency ripples, thereby enabling the adjustment of polishing parameters.

4. Stress-Induced Deformation Detection

When optical components are mounted into fixtures or lens cells, they may undergo slight deformation due to stress, which adversely affects their surface figure. Optical profilers can guide mechanical designers in optimizing the support structure and mounting scheme to mitigate this stress, ensuring the component maintains its optimal surface form during operation.
