Measurement of Negative Focal Lengths

MELOS

Collimator projects a reticle to infinity. The specimen produces a virtual image of the reticle in its focal plane. The measurement of the size of the virtual reticle image with a reading telescope consisting of an autocollimator and an attachment achromat gives the focal length. The measurement process is done menu-controlled by the display unit.
