Disappointing lens, poor quality optics

The Double Convex Lens Diameter Length from this brand was a complete letdown. As my tests showed the optics are poor quality, resulting in fuzzy and distorted images. It's unfortunate that a product in this category of Industrial and Scientific equipment could be so subpar..

Pros
  • Easy to handle
Cons
  • Poor quality optics

Revainrating 4 out of 5

Decent quality

Good lens, right size and focal length but optically not very good. The surface is riddled with very small dents that are not noticeable when working with low accuracy.

Pros
  • Optics
Cons
  • No performance
