Abstract: An apparatus for operating an endothelium reflection microscope. The apparatus includes an optical head, which comprises: (i) an illuminating system, (ii) a frontal eye observation optical system along a central channel in which an alignment-use light spot is received and imaged by a camera having a digital optical sensor, and (iii) an enlarged-imaging optical system for enlarged observation or photographing of the subject part by the digital camera. The apparatus further comprises a motor for operating the optical head, and a CPU controller for automatically controlling the motor, the illuminating system and the frontal eye observation optical system.

Abstract: An apparatus and a method for operating an endothelium reflection microscope. The apparatus comprises an optical head including: an illuminating system, an eye-front observation optical system along a central channel in which an alignment-use light spot is received and imaged by a camera comprising a digital optical sensor, and an enlarged-imaging optical system for enlarged observation or photographing of the subject part of the digital camera. The apparatus further comprises a drive for moving the optical head and a CPU controller for automatically controlling the drive, the illuminating system and the eyefront optical system.

Abstract: A test pupil device for Corneal Topography, having a videocamera in sequence with an optical group including lenses, an outside Placido disk, a fixing LED, an infrared fixing LED, a neon glow lamp and including at least one beam splitter plate. An infrared LED may be placed laterally onto the Placido disk or away from the Placido disk and is provided so to provide for a grazing light for the pupil test. The lateral LED and the fixing LED are infrared LED's so as not to interfere with the light sources to be used for the cornea test that uses frequencies in the visible light range.

Abstract: A stereoscopic microscope which makes use of two pairs of lenses, each pair having a different magnification. Both pairs of lenses are supported in a disk-shaped drum along a pair of orthogonally related diameters and rotatable through an angle of 90.degree. by a draw lever to place the two pairs of lenses alternatively in position for use by an operator for a direct observation of the image of the patient's eye structure and for all operating functions of a video recording camera. The optical scheme makes use in one direction of a right-angle prism arrangement for deviating rays from a patient's eye in an opposite direction, towards the video recording camera.

Abstract: An optotype projector apparatus provided with variable contrast, and having a large variety of optotypes and matrices for providing tests for stereoscopic vision of chromatic balance and comprising a projector for producing contrasting variations of the optotype images operating on the basis of two complementary light sources, one provided by a primary body and the other provided by a secondary body, both of which are remotely controlled so that by diminishing the intensity of one source, a consequent increase of the other source takes place.
