Customer Reviews (4.2 / 5 · 5 reviews)

Daniel E. ★★★★★

Got this for a new optical bench setup and the long working distance really makes alignment easier. Fringes were crisp and stable right out of the box.

Joshua ★★★★★

Swapping to this 20X objective was a noticeable upgrade for my interferometry work—the 0.40 NA gives a much clearer fringe pattern than my old lens. The long working distance is a lifesaver when I’m measuring samples with taller features.

Violet B. ★★★★☆

The long working distance makes it much easier to align samples under the 20X objective compared to my previous setup. Image quality is sharp across the field, which was exactly what I needed for precise surface measurements.
