Broadband Dielectric High-Reflectivity Mirror
Broadband dielectric high-reflection mirrors provide nearly total reflection to minimize optical losses. At AOI=45°, R>99.5%, with Rs>99.9% and Rp>99.2%; at AOI=0°, R>99.8%. Durable coatings are easy to clean and resistant to laser damage. Multiple transparent optical-material layers provide high reflectance, a high damage threshold and low scattering for medical imaging, lasers and aerospace. Other sizes, shapes and coating designs are available.

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.
