Although measurements are taken using expensive MTF measuring instruments that ignore the cameras, image sensors, and lighting equipment that are actually used, many people complain that the results do not match the actual results. Therefore, we measured SFR (Special Frequency Response) using the camera, image sensor, and lighting equipment that would actually be used. If measurements can be taken from the beginning, taking into account the camera and lighting equipment that will actually be used, it will be easier to analyze the cause.
・Real-time measurement of overall contrast by simply using a dedicated chart and software in an actual environment
・An excellent product that can detect lens assembly defects by simultaneously measuring the contrast at any position.
■Applications
・Quantification of lens performance evaluation
・Existing lens evaluation measurement/analysis
・Eccentricity during lens assembly/adjustment, SFR evaluation/measurement
