An actuator pivots a reflecting lens to switch viewing directions, eliminating adapter replacement and reducing inspection time.
Objective optical system uses plane-parallel plate and segmented lens groups to maintain wide angle of view while preventing excessive lens diameter.
Shipping containers integrate lenses and hinges to support mobile devices, resolving the cost versus quality trade-off in virtual reality access.
An optical scanning attachment integrates a laser, conical mirror, and wide-angle lens to project structured light patterns onto target surfaces.
Optimizing lens radii and curvatures reduces curvature of field, astigmatism, and coma while maintaining high resolution in a compact wide-angle design.
A single reversible motor drives a threaded lead screw to position laser interference filters in night vision devices.
Ratchet structures in the locking eyecup prevent incidental movement during use, ensuring steady position stability.
