4" Verifire ATZ

The Zygo certification number on the unit gave me real peace of mind that I wasn’t getting a questionable refurb. The 4-inch aperture with the Ring of Fire upgrade makes the fringes pop so clearly, and setup took me less time than I budgeted for.

The Ring of Fire upgrade makes alignment checks noticeably faster—I had fringes dialed in within minutes of unboxing. The 4-inch aperture feels solid and the Zygo certification paperwork gave me confidence it’s a genuine unit. Exactly what a metrology bench needed.

Setup was straightforward, and the Zygo certification paperwork gives me real peace of mind about the accuracy. The 4-inch aperture with the Ring of Fire makes alignment checks much quicker than I expected.
