Review: Fine Objective Lens for Specific needs: a wide, flat field of view. Not for greater depth of field. - An excellent lens for its purpose, which is to focus on tiny things in nearly a single plane. Great for larger bacteria, or with a higher power eyepiece (15X, 20X, 25X...), for typical-sized bacteria, blood-cell counts, etc. A "Plan" or "Planar" lens also provides the widest field of view, but does not have great depth of focus for larger objects, so this is a specialized lens for a specific purpose. One problem, though...when it arrived, the outer lens casing was loose, not properly tightly screwed on, and this was the case with some of the other objective lenses I've purchased...
Review: Significant Improvement in Overall Image Quality - This Amscope 40X Plan objective lens significantly improves the overall image quality. It is much sharper, has higher resolution, contrast, and produces a significantly brighter image than the stock (non planar) lens. Equally importantly, the image is much sharper around the perimeter. Somewhat expensive, but definitely worth the cost. Highly recommended. Just be careful when installing and when focusing, as the tip of the lens needs to come precariously close to the cover slip in order to focus. If your microscope has a stage stop mechanism, we would recommend adjusting it as a precaution to prevent accidental contact with the slide.

Correcting a review. I am impressed with this objective compared to my non-PLAN objective. A worthwhile upgrade.
