Mirrors and Partial Reflectors RFS-20-2U
total Reflector is used either within a laser cavity as rear mirrors or folding mirrors, or external to the laser as bending mirrors to deliver the beam to the work. Silicon total reflector is the most common used mirror for laser system, it has good durability, thermal stability and relatively low cost. Copper mirror is typically used for high-power laser system, it has high thermal conductivity. Molybdenum mirror is normally polished only, without coating, used for tough environments. it has extremely tough surface.

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.
