Zeiss Use of MALS is "The Biggest Breakthrough in Microscopy Since the Invention of Microscope"

Zeiss Visioner 1 digital microscope uses SD Optics' Micro-mirror Array Lens System (MALS) technology to achieve digitally-extended depth of focus up to 69mm:

"ZEISS Visioner 1 revolutionizes the world of optical inspection and documentation. Driven by the unique Micro-mirror Array Lens System (MALSTM technology), enables for the first time, real-time all-in-focus imaging – first time, every time.

Using a micro-mirror array lens system (MALS™) enables us to generate “virtual” lenses with distinctly different curvatures, thus different focus planes. This is achieved by changing the orientation of each individual micro-mirror in an orchestrated way.

Re-shaping the curvature of this “virtual” lens at speed enables ultra-fast focusing and real-time all-in focus imaging and documentation.
"

  • Up to 100x more usable Extended Depth of Field
  • Allows for height differences of up to 69mm*
  • Reflective micro-mirror array with curvatures (variable) arranged in a flat plane
  • Each micro-mirror is about 100x100 µm
  • Each micro-mirror rotates & translates to form the optical surfaces with variable curvatures
  • No need for Z-stacking or re-focusing
