Beam shaping unit BSU-6000

Beam Shaping Unit is intended to be applied in laser systems for micromachining applications to create round or square laser spots with uniform intensity distribution.

Beam Shaping Unit is intended to be applied in laser systems for micromachining applications to create round or square laser spots with uniform intensity distribution. BSU-6000 was developed by AdlOptica and technically implemented by Workshop of Photonics at Altechna R&D. The BSU-6000 is developed to operate in combination with customer’s scanning optics and is based on refractive field mapping beam shaper piShaper. Output of the piShaper is imaged onto a workpiece by imaging optical system composed from an internal collimator and external lens, for example F-theta lens of the customer’s equipment. The unit will be installed and adjusted by an engineer from WOP. Any additional requirements from the customer should be noted as early as possible.
