Assembled Optical Window
Assembled optical windows are important components of laser levels. Made from high-precision optical windows, they transmit laser beams and provide a clear, unobstructed view of the target surface. Surfaces are polished to minimize roughness and defects, and high-quality bonding materials secure the windows. Most have antireflection (AR) coatings to improve transmission and measurement accuracy.

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.
