Lens module

摘要

A lens module includes a non-cylinder lens and a clamping apparatus. The clamping apparatus includes a base, two side parts, and a top part. Two side parts are disposed on two ends of the base to form a containing trough for holding the lens. One end of the top part is connected to one side part and the other end is fixed on the other side part. Two screw holes on the top part allow two adjusting screws to be screwed into for pressing the lens. Two elastic devices provide the elasticity between the lens and the base and the relative height of two sides of the lens is adjusted by turning the two adjusting screws.
