It is high-power zoom Laser beam expander.
It supports a broader wavelength range than the current models.
It can be used in an optical system with high precision, such as a laser interferometer and processing by the lens design that takes into account the wavefront aberration.

◦The optical design of the beam expander is an air gap configuration that does not use an adhesive to bond the lenses. This allows the beam expander to be used with a high-power laser.
◦It is designed and coated to enable to use in a broader wavelength range than the current models.
◦By turning the diopter ring that is attached to the center of the beam expander, you can make variable beams such as the focused beam, collimated beam, and the divergent beam. It is used when you want to vary the position of the beam waist and if strict collimation adjustment is necessary.

▶We provide the laser beam expander holders (KLH-BE) for optical axis adjustment of the laser beam expander.
W4147

Attention

▶The laser energy density at small aperture(output aperture) will become higher than LIDT when reducing the beam diameter and the Beam expander might be broken.
▶It may not be able to obtain the expected function when the beam expander is used in the opposite direction (reducing the beam diameter). Please refer the technical note of he laser beam expander for details.
