SD OPTICS developed an optical module names 'WiseTopo', a 3D digital optical module using MEMS-based lenses that converts a two-dimensional (2D) microscope into a three-dimensional (3D) microscope. Regardless of the model, by just attaching the module, it will convert them into 3D.

WiseTopo™ is characterized by overcoming the limitations of 2D microscopes with fixed focus which can used by mounting a module instead of an existing microscope image sensor.

The range recognized as being in focus during shooting is called depth of field (DoF), and 2D microscopes have very limited DoF. The plane can be seen from above, but the exact shape or height change of the object cannot be easily detected. Solving this problem requires refocusing manually or with a Z-axis (height) motor, which is inconvenient and less productive.

WiseTopo™ is to overcome these limitations with their own 'ultra-high-speed varifocal' lens technology. The varifocal lens applied to the module contains thousands of micromirrors. Each micro-mirror moves at a high speed and focuses without any separate Z-axis movement. Through this, 3D images and various data can be extracted.

WiseTopo™ provide,

- Depth of field expansion function

- Real-time 'all-in-focus' that focuses in all areas

- 'Fast auto focus' that automatically focuses on the desired area

- Real-time 'multi-focus lock' function that maintains focus even when the sample is moved.

SD OPTICS’ Vice President Kyung-Suk Jeong said, “It is an innovative technology that can evolve existing 2D microscopes into high-priced 3D microscopes, and we are proud to build the foundation for popularization of 3D microscopes. We plan to upgrade performance and functions so that we can target the bio microscope market in the future.”
