This instrument places an illuminated object of known size ata known distance p fromthe cornea, which then reflects some light from the object, formingan image of it. The magnification Mof the image is measured by using a small viewingtelescope that allows a comparison of the image formed by thecornea with a second calibrated image projected into the field ofview by a prism arrangement.
