High-Power Laser Beam Expander
BEHP-4-250/280
These laser beam expanders are designed for use with a high-power laser.
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.
