Product Advantages
Beam expander for CO2 lasers with fixed, variable or zoom magnification and ZnSe optics.
Beam expanders have two main purposes in the laser industry.
•Increased power density in the focal point
•Beam guidance over long distances
Beam expanders consist of two lenses that are built according to the Galileo principle and therefore do not generate an intermediate focus. These systems are suited for typical medium power levels of up to 100 W. There are different designs:
Fixed expanders are inexpensive systems in which the focusing range cannot be readjusted. Variable Expanders
With variable expanders, the spacing between the lenses can be modified to compensate for the divergence of the incident beam. The total length can vary by ± 3 mm.
In zoom expanders an infinitely variable magnification level can be set ranging from 2 to 8 times the original size. Due to the high variability, these expanders are quite common in the laboratory.
The expanders are variable. That is to say, compensating for divergence/convergence is possible.
When used in reverse, beam expanders can reduce the beam diameter.
