Instantly measure the deviation of the focus position and contrast relative to the reference lens! Measurement of focal length.
It can instantly and quantitatively measure the amount of focus shift due to aperture, not only for fixed lenses and zoom lenses. It can measure the focal length error. By projecting a chart onto the lens and scanning a mirror placed on the image plane up and down, it precisely counts the focus position. With 16 levels of sensitivity adjustment, it has a wide measurement range and supports various types of lenses. It is capable of RS232C communication, making data control via PC easy.
