12" Beam Expander- Wavelength Shifting/ DynaPhase

The phase stability on this unit is rock solid—my HD-MST setup finally gives clean, repeatable data without the mechanical phase noise I was fighting before. Setting it up took minutes, and the 12-inch aperture handles the full beam path flawlessly.

I was nervous about dropping this into our DynaPhase setup, but the alignment was dead-on straight out of the box. The 12" aperture gives me plenty of room to shape the beam without clipping, and swapping it between the HD-MST and our older unit took maybe two minutes. Solid piece of glass.

The 12" beam expander threaded right onto my HD-MST without any adapter fuss, and the alignment stayed dead-on through a full afternoon of wavelength shifting runs. I was worried the DynaPhase side would drift without mechanical phase adjustment, but the readings held steady. Solid piece of glass, n
