200F Series Automatic Focometer

A digital focal length measuring instrument is an optical metrology device used to measure the effective focal length of lenses.It adopts a digital area-array detector to receive optical images in place of the traditional visual observation system.Through image processing algorithms, it accurately extracts feature information of the test target, delivering higher measurement accuracy.The motorized focusing mechanism ensures that the sharpest focal plane can be located each time, free from human subjective interference.The intuitive software interface makes the whole measuring process simpler and more efficient.
