Each laser application requires a certain spot diameter; this depends on the beam diameter of the laser used.
To achieve the largest possible power density in the focal point, the collimated beam is expanded to its maximum. Incidentally, this reduces the divergence of the beam.
For high laser power. The beam expanders introduced here are designed according to the principle of the Galileo telescope; they do not have an intermediate focus. Thus, our beam expanders function at a laser power of up to 100 W. Standard expanders are available for the wavelengths 10.6 µm (CO2), 1064 nm (Nd:YAG), 532 nm, and 355 nm.
Fixed and variable expanders.
In variable expanders, the distance between the lenses can be changed in order to compensate for the divergence of the input beam. The entire length of the system varies by ±3 mm. Expanders with a fixed focal length do not allow these types of adjustments and are particularly inexpensive.
Zoom expanders.
These expanders allow a smooth magnification of 2x to 8x, which is the most common version. These expanders are variable and have the above-mentioned advantages. Due to their flexibility, they are particularly well suited for laboratory applications.
