Owen ★★★★★

The 60 mm parfocal length made swapping it into my setup seamless. Image clarity at 0.15 NA is crisp for my test slides. Very consistent performance so far.

Madison F. ★★★★★

I paired this with my existing Michelson setup and the 5.5X magnification gave me sharper fringes than my old lens. The 0.15 NA provides just enough light gathering for my interferometry work.

Hannah O. ★★★★★

The 60mm parfocal length made swapping it into my existing Michelson rig completely painless, no re-collimation headaches. At 5.5X with that 0.15NA, the working distance feels generous and the image stays flat across the whole field. It's doing exactly what I hoped it would for interference fringe w
