Non-Polarizing Beamsplitters Cube (No energy loss)
Applying dielectric coating only instead of hybrid metallic coating, the non-polarizing beamsplitter will get no energy loss. The transmittance and reflectance can be precisely controlled to 50%. Design only by dielectric coating only. Energy loss negligible Transmission of P-pol and S-pol are very close to 50% with ±2% Available only for Narrow Wavelength

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.
