摘要： A visual function measuring apparatus includes a visual target displaying device for presenting visual targets of different sizes successively to an eye to be examined, and a response inputting lever for inputting the response of an examinee to which the visual targets have been presented. The examinee's visual function is measured on the basis of the response input. The apparatus also includes a controller for controlling the device so that the visual targets presented to the examinee by the visual target displaying device may be changed in succession from a smaller visual target to a larger visual target.

摘要： An ophthalmological apparatus is arranged in such a manner that different measuring light sources are provided for an eye refractive power measuring system and a lens refractive power measuring system. A light sensor of the lens refractive power measuring system is commonly used as at least either the light sensor for an alignment observing system or the light sensor for the eye refractive power measuring system. A lens to be examined can be placed at a position which is different from a position where an eye to be examined is placed.

摘要： A catoptric system adapted for X-ray fluoroscopic photography comprises a spherical concave reflector disposed to reflect fluorescence light coming from the object plane to a field flattener of positive power positioned in front of a photographic film. In one embodiment of the invention, the reflector is constituted by a negative meniscus lens having a primary surface facing the object plane and with the secondary surface being mirrored. In order to facilitate minimization of the reflector diameter, there is provided a positive meniscus lens, having a concave surface facing the object plane, positioned between the reflector and field flattener to thereby assist in converging the rays of light from the object plane before impingement on the reflector.
