摘要： Disclosed is a laser spot projector for use with a laser coagulation system in which a laser beam is radiated as a focussed spot into a portion selected to be thermally coagulated. A laser source produces a laser beam, and a focussing lens focusses the laser beam on the selected portion in the form of a focussed laser beam spot. A variator lens is displaceably arranged between the laser source and focussing lens for changing the magnification of the laser spot depending upon the displacement of the variator lens. The variator lens is selectably displaceable to two separate positions where the image point is conjugated with the object point with respect to the variator lens. This arrangement makes it possible to selectably provide two focussed laser beam spots each having a different spot diameter.

摘要： A laser coagulation system adapted for use in an ophthalmological treatment comprises a slit image projector for projecting a slit image into the eyeball of a patient to determine a selected portion of the eyeball to be coagulated, and a laser beam projector for projecting a laser beam onto the selected portion. Both the projectors include a common reflecting means which is divided into two side portions for directing slit light toward the selected portion to be coagulated, and a central portion between the two side portions for directing the laser beam toward the selected portion thereof.

摘要： An apparatus for detecting ophthalmic disease such as a cataract in the lens of a patient's eye includes means for focussing a laser beam and slit light alternatively or simultaneously at a selected spot in the lens of the eye. The slit light is used in a monitoring or adjustment mode to illuminate the selected spot and its adjacent portion on which the laser beam is to be focussed for ophthalmic disease detection, thereby making easier the identification of spots to be measured in the lens of the eye.
摘要翻译：用于检测患者眼睛的眼睛中的眼部疾病如白内障的装置包括用于在眼睛的晶状体中的选定位置处交替地或同时地将激光束和狭缝光聚焦的装置。狭缝光用于监视或调节模式以照亮所选择的光点及其相邻部分，在该部分上激光束将被聚焦以进行眼科疾病检测，从而更容易地在眼睛的镜片中识别要测量的斑点。
