Robert U. ★★★★★

Took a gamble on this for our lab's optical setup, and the mechanical phase shifting is rock-solid—zero drift during a 20-minute test run. The 18-inch aperture feels massive, and the standard SKU config was exactly as listed.

Eva ★★★★★

The mechanical phase shifting on this 18" expander is smooth and repeatable, and it held alignment perfectly after I swapped it into the setup. Took a bit of care mounting it given the size, but once dialed in the wavefront looked clean.

Sophia U. ★★★★★

Wasn't sure what to expect ordering optics online, but this 18" expander arrived well packed and collimated right out of the case. The mechanical phase shifting adjustment has barely any backlash, which makes dialing in the fringes way easier than the older unit I used. Build feels solid enough that
