Turning Lens
A turning lens is a special-shaped lens that can be regarded as a combination of a plano-convex Clens lens and a right-angle prism. A single component can provide beam divergence, convergence and redirection. For example, a parallel incident beam can be redirected by total internal reflection at the inclined surface and focused onto a photodetector (PD), saving device space and enabling further miniaturization.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
