●High Performance Beam Expander
It reduces losses and suppresses beam quality degradation, thermal lens effect by minimizing number of configuration lenses. It achieves compact size with short focus lens and suppresses beam axis deviation.
Galilean designs, combining a convex lens with a concave lens, is adopted for the lens configuration. This configuration doesn’t have a focal point can be used with high-power lasers. It has a beam divergence adjustment mechanism. It is available a fixed magnification and variable magnification (zoom).
●Zoom Collimator
Spot diameter (transfer magnification) can be continuously varied, adaptable to various processing.
Adopting aspheric lenses reduces aberrations and realizes zoom function with two lenses.
