Distortionless and High Performance Machine Vision Macro Lens with a floating system

What is a floating system?

Normal lenses shift just a single group of elements for focusing. Additional floating elements (see picture on the left) can improve the close-focus performance significantly.

Because the floating component is separate to the focusing lens group, aberrations caused by lens extensions are significantly reduced. Benefits are particularly great in macro lenses because they cover a wide range of focus distances and in wide-angle.
