Abstract
An objective lens anti-shock adjustment device comprises a holder that is capable of fixedly holding an objective lens via at least a fastening element. The holder is mounted in a casing by means of a plurality of resilient elements and a plurality of adjuster screws. The resilient elements connect the holder to the casing and the adjuster screws engage through the casing and abut against the holder opposite to the resilient elements in order to allow the adjustments of a vertical positioning and a horizontal orientation of the objective lens. The holder and the casing are provided with respective openings that expose a slot formed on the objective lens. By the external engagement of a tool through the openings into the slot, the objective lens is slid in the holder in order to adjust the depth of focus.
