Design
  • Diffraction-limited design
  • 5 element design reduces internal focus
  • Continuous zoom and focus adjustments
  • Mechanicals specifically designed to minimize
    beam wander

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.

At Special Optics, we employ a proprietary 5 lens-element design with 3 lens groups to reduce the internal focus.  Also, we use fused silica lenses on the two input groups.  As a result, our zoom beam expanders tolerate a very high damage threshold.
