| Product Summary: |
Features
- Scratch-Dig: 20-10
- Wavefront Error:
- Damage Threshold: 100 W/cm2 CW
- AR Coating: R<0.5% Over Coating Range
- Post-Mountable via 8-32 and M4 Taps
- Dimensional Length: 189 - 195 mm
This Galilean Beam expander comes with a 2X to 5X continuously variable beam expansion ratio. The expansion ratio can be adjusted from the minimum to the maximum value via one full rotation of the zoom control. Once the desired magnification is obtained, a setscrew can be tightened to lock the magnification. Please note that the induced wavefront error varies with the magnification ratio. The housing features both 8-32 and M4 taps for mounting. Additionally, this housing has a Ø2" portion so that it can be mounted in our KS2 Ø2" mirror mount.
