The laser beam is split into two orthogonal polarization components.
The cube beam splitter consists of two right-angle prisms coated with a special dielectric coating. The polarizing cube beam splitter divides a laser beam into two orthogonal polarization components or is used to combine them into one beam. It transmits P-polarization and reflects S-polarization at 90°. In low-power applications, the cube is assembled using a transparent refractive index matching adhesive at the junction with two 90° right-angle prisms. It can be used up to 1064nm at 1 J/cm². Please enter from the marked surface. Optical contact cubes offer good beam quality, high damage thresholds, a wide wavelength range, and wavefront accuracy, but they are not mechanically stable due to the fragile nature of the optically contacted interface. The new molecular fusion bonding technology from Spectral Optics permanently bonds without using cement or other materials that degrade coating performance.
