Broadband antireflection-coated achromatic lens
Achromatic lenses reduce or eliminate chromatic aberration, and their design also helps reduce spherical aberration. They are ideal for fluorescence microscopy, image relay, inspection, spectroscopy, and other applications. Usually made from two cemented elements or two elements mounted in a mechanical housing, they produce smaller spots than comparable singlet lenses.

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.
