GEODESIC INSTRUMENT WITH A STABILISATION ELEMENT FOR FITTING AND ADJUSTING AN OPTICAL ASSEMBLY IN A HOLDER AND METHOD FOR FITTING THE STABILISATION ELEMENT

摘要

The optical instrument comprises optical assembly (1b) with several optical element such as lens which defines an optical axis (8). An optical assembly holder (1a) has a shape so as to form a gap (13) with defined width between the optical assembly and holder. A stabilizing component (2) comprising stabilization elements (3a-3c) for stably connecting optical assembly and holder is provided in the gap. The stabilizing elements are deformed, so that elastic forces are acted on optical axis between assembly and holder in radial direction. The thickness of stabilizing element in an unassembled state is greater than width of gap. The optical assembly, holder and stabilizing component are connected in coarse-positioned state by inserting the optical assembly into the holder. An independent claim is included for method for mounting optical assembly to holder.
