Motorized Zoom Beam Expanders
At Special Optics, we employ a proprietary 5 lens-element
design with 3 lens groups to reduce the internal focus.
We use fused silica lenses on the two input groups. As
a result, our zoom beam expanders tolerate a very high
damage threshold. Other beam expanders contain 4 lenses
consisting of 3 lens groups, the first being positive followed
by a negative group, then a positive group for collimation.
This design causes a focus into the second lens group,
consequently increasing the possibility of damage to the
system.
Design highlights:
• Diffraction-limited design
• 5 element design reduces internal focus
• Mechanical design minimizes beam wander
• Continuous zoom and focus adjustments
Design
• Default expansion settings pre-programmed
• User defined custom expansion settings
• User-controlled focus adjustment
• Windows compatible
• RS232 Serial Interface
• Compact design
• GUI (.DLL) can be addressed from C++ or other languages
