Abstract

PURPOSE:To measure photometry for the desired position in the screen without losing framing, by providing the projection optical system in which a plurality of photo detectors are located in scattering between the measuring optical system and the observed image to move the light emitting elements corresponding to the photo detectors. CONSTITUTION:The light flux from the inspected eye 2 illuminated with the slit light flux from the illumination optical system 1 is parallel through the objective lens group 3, and after the beam splitters 4, 14, 24 of the first, second and third, the observed image of the inspected eye is formed on the focus 6 of the second objective lens 5 and it can be observed through the eyepiece lens 8. The light of the first splitter 4 is picked up on the film 11, the light flux from the second splitter 14 is formed on the photo electric converters 17a... located in straight line with plurality, and the light flux from the third splitter 24 is inputted to the light emitting diodes located corresponding one to one to the elements 17a.... The inspector 7 can observe the image of tested eye on the image of the light emitting diode 27, and when the light signal from the element 17 corresponding to this image is used as the light measurement signal, suitable photometry can be made without losing framing.
