Note: The ML series microlens array are cost-effective product line. Mainly used for Medical beauty, Shack Hartmann sensor, High sensitivity imaging, Wavefront sensing, Beam focusing and some other applications. Due to the limited level of our cleanroom in old factory, there are always some defects (bad spots) on the surface of ML series products. The surface accuracy is also not very good.

Sophisticated 3D printing technologies offer a high level of design flexibility and a high resolution in printing. Therefore, the printing of optical elements is an advantageous alternative to conventional production procedures.

With this procedure 3D-printed optical elements can be functionalized. By filling microcavities after printing, components such as diaphragms, color filters or achromatic lenses can be directly integrated into the design of the optical components. If a ferrofluid is used as a filling, multi-lensed zoom or focusing systems can also be realized.

The 3D printing of optical elements has increasingly gained importance in recent years, as it is often more flexible and inexpensive than conventional micro molding processes. 3D printers that can produce complex optical systems are available on the market. Until now, however, one weakness has been that the component to be printed has to be completely transparent in the near infrared range, in particular in the stereo-lithographic procedure. Therefore, no absorbing areas can be printed into the optical system. In addition, the printed components have been rigid until now and could not be made tunable, for example by external actuation.

Printed optical elements with functional areas such as diaphragms and structures for scattered light absorption can now be simply and inexpensively produced by using microfluidic structures. These structures are integrated into the print layout of the optical components and are formed during the 3D print. If a ferrofluid is used in the process, controlled forces can be exerted using a magnetic field, thus realizing active systems.

As part of a project sponsored by Baden-Württemberg Stiftung gGmbH, scientists at the University of Stuttgart have now developed a new procedure. Functional areas, such as diaphragms and structures for absorbing scattered light, can now simply and precisely be integrated in complex printed 3D optical systems. For this purpose, the micro-optical element is already provided with the smallest of hollow spaces (micro cavities) during printing. These cavities later serve to intake functional substances. The small size of the hollow spaces mean that capillary forces carry out the distribution of liquid in the hollow spaces. The functional liquid is then dried or hardened. Properties such as the absorption, reflection or scatter properties of the functional areas are precisely defined through the choice of the substance, i.e. the nano particles it contains. If the hollow spaces are filled with a ferrofluid, the physical properties can be additionally changed by a magnetic field. In this way, multi-lensed zoom or focusing systems are possible which can for example be directly printed onto an image-conductive fiber.
