Abstract: Stimulus light is projected from a stimulus light source onto an ocular fundus of an eye under examination to locally stimulate the retina in order to perform a biological examination. During a biological examination, first background light is projected from an illumination light source via an objective lens, and second background light is projected from a light source from the periphery of the objective lens onto the ocular fundus.

During observation of the ocular fundus, the first background light projected onto the fundus is blocked, so that fundus observation or eye fixation is not disturbed by the background light. This enables accurate alignment to be carried out.

Abstract: A uni-planar focal adjustment system involving no reflector housing rotation for use in high-intensity discharge (HID) lighting systems. A simple mechanical drive system allows a user to manually adjust the focal point by turning a focal adjustment ring, which in turn moves a HID lamp assembly back and forth along an optical axis relative to a stationary reflector.
