Abstract

1,143,138. Optical apparatus. HUGHES AIRCRAFT CO. Oct. 10, 1966 [Nov. 1, 1965], No. 45108/66. Heading G2J. [Also in Division H1] A laser is associated with an alignment microscope and means are provided for determining respective focal planes for the laser beam and for the microscope light path, the relative displacement between the focal planes being adjustable by controlling an optical system in the light path of the microscope and not in that of the laser beam. An enclosure 49 is mounted on a housing for vertical movement in response to rotation of a lead screw. The housing contains a laser, the output beam from which is deflected by a dichroic mirror beam splitter 51 to pass through an objective lens 72. The mirror 51 is transparent to radiation at wavelengths other than that of the laser beam and so transmits light from object 76 through optical system 86 Fig.5 to microscope eye-pieces 82. The optical system includes a reticle 92, lens system 96 and a movable lens holder 98. The lens holder is mounted for vertical non-rotary movement in response to rotation of a focusing cam having adjustable cam surfaces 111, 112, and is biased downwards by a spring 103. If the lens holder is adjusted so that the focal plane for the microscope is above or below that for the laser beam, when the microscope is focused on object 76 the laser beam is focused to a point such as 75 and the laser energy is directed on to a spot of known diameter on the object. If the focal planes coincide the laser beam impinges on the object with minimum spread and maximum energy.
