MELOS (Measuring Equipment for Lenses and Optical Systems)Measurement of Positive Focal Length The collimator projects a reticle to infinity. The specimen produces an image of the reticle in its focal plane. The size of the reticle image is determined solely by the known focal length of the collimator objective and the focal length of the specimen to be measured. The measurement of the size of the reticle image with a reading telescope consisting of an autocollimator and a microscope objective gives the focal length. The measurement process is done menu-controlled by the display unit. A solution for shorter focal length is available on request.
