Candela Gmax Pro and Gmax Beam Combiner
The beam combiner in your laser allows the 755nm (Alex) wavelength to pass through while reflecting the 1064nm (Yag) wavelength.The beam combiner is used to align the YAG laser beam into the fiber because the focusing lens is fixed. Both sides of the beam combiner are coated. One side uses an AR coating maximized for 755 nm and the other side is coated for maximum reflection at 45 degrees.
