About This Product

■Summary

Characteristic evaluation of aspherical lenses can be performed easily and quickly.

■Evaluation method for aspherical lenses

When evaluating a lens using a coordinate measuring machine, it is possible to accurately measure the shape of both the front and back surfaces, but it takes a lot of time to measure the surface. Lenses that meet the evaluation criteria are then made into a set and evaluated using MTF, etc., but when an NG occurs, it is difficult to identify the cause. Features

■Optical properties can be evaluated

By using a null mirror as the reference lens, it is possible to measure the transmitted wavefront of an aspheric lens, and by using a spherical mirror, it is possible to measure the transmitted wavefront of a set of lenses. Unlike a normal transmitted wavefront measuring device, by following this point image from a reference lens, various parameters for evaluating the lens were calculated from each clause of the ZERNIKE coefficient. Problems inside the lens that cannot be detected by shape evaluation alone become clear.

■High-speed measurement without being affected by vibrations

The analysis method used in the carrier fringe method calculates the wavefront from a single image, so it is not affected by external vibrations, and accurate measurements can be made if vibrations are suppressed even during the image acquisition time (0.2 seconds). You can. This enables real-time measurement at the processing site or during adjustment.

■Equipment advantages

・Optical evaluation of lenses is possible in a few seconds ・Can detect optical details inside the lens ・Cheaper than probe type coordinate measuring machine ・Possible to eliminate defective lenses before installing them ・You can isolate whether the problem is with the lens itself or during assembly.
