Abstract
760,881. Indicating-apparatus. HENSOLDT & SOHNE OPTISCHE WERKE AKT.-GES., M. Sept. 24,1954 [Oct. 23, 1953], No. 27633/54. Class 106 (4). [Also in Group XX] A device for reading a scale consists of an eyepiece movable along the scale and having means whereby a graduation not on the optical axis of the eyepiece is shown in unaligned halves, the objective of the eyepiece being adjustable to align the halves giving subdivisions of the units between the graduations on a scale in the eyepiece, the subdivisions being added to the whole units read directly. Light rays from the scale 3 pass through the objective 2 and a semi-reflector 5 to prisms 6, 7 which each transmit one half of the rays. If the eyepiece optical axis is not directly over a graduation, the scale will appear as shown in Fig. 4. The objective is mounted on a slide 12 which is movable by a rotatable cam 17 and a lever (not shown) relative to the eyepiece along the scale until the half graduations are aligned. This movement is then readable on a scale 19 fixed to the cam 17. The device may be used in refractometers. In another embodiment (not shown) the optical system includes a tiltable plane parallel plate system adjustable through a measured angle to produce coincidence.
