HUDSON, N.H., March 19, 2015 — Variable beamsplitters from Laser Components USA Inc. have an inhomogeneous layer distribution on a square substrate. The components are used to incorporate two beams in an assembly with a single laser when the laser power of both partial beams is meant to be identical following the last optic in the system. This is impossible with conventional beamsplitters because the different components transmit light unevenly. The beamsplitters are based on customer request. The designs depend on the wavelength: If a variable beam splitter is developed for 532 nm, it does not function at another wavelength. For example, for 1064-nm designs, transmissions from 45 to 55 percent and 10 to 70 percent are available, or for the wavelength 753 nm, transmissions from 4 to 20 percent are available. Two standard sizes are offered: 45 × 22 mm and 70 × 22 mm. Other sizes are available, but the maximum length of the substrates is restricted at 70 mm.
