Abstract
PURPOSE:To facilitate the cementation of two lenses or its automating by irradiating two lenses with aiming light, by detecting the deviation of reflected light from the axis of the aiming light, and by cementing two lenses together by sliding them along a common center line after the optical axes of both the lenses coincide mutually. CONSTITUTION:Two lenses 2 and 3 are held by lens holders 12 and 13 through adsorption with their cemented surfaces facing to each other, and the fitting piece 22 of a mirror 7 is fitted in a fitting hole 21. The lens 2 is slightly moved back and forth for the adjustmented of optical path length and through an eye piece 20, reflected light from the lens 2 is measured on an image formation surface 191 with the naked eye. If the optical axis of the lens 2 coincides with a common center line l, aiming light from a light source 15 image-formed at a point P through a chart 16, half-mirror 17 and objective lens 18 is reflected by the lens 2 at the point P to form the optical image of the chart 16 at an intersection Q. Similarly, after the optical axis of the lens 3 is matched, an adhesive is applied and a knob 111 is turned to bring the lens 3 into contact with the lens 2 for cementation. Thus, the cementation or its automating is facilitated.
