Design
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.

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

Features:
RS232 Serial interface

One motor control box

Default expansion settings pre-programmed

User-controlled focus adjustment

Users can define custom expansion settings

Compact 2" outside diameter for standard optical mounting

Windows compatible
