Achromatic Lens
A chromatic aberration-free lens is an optical component with a special design that reduces chromatic aberration (the difference in the focusing positions of light of different wavelengths). The core principle is to utilize the difference in the dispersion characteristics of different materials for light, and to focus light of various wavelengths as closely as possible at the same point. It is composed of two or more singlet lenses, and is fixed using bonding or assembly structure.

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.
