LAB7 - QXXLF

A wide variety of different sensors will be used in the automobiles of the future. As part of the ICM project SdManu1, it was shown how complex lenses for optical sensors can be manufactured at low cost. To this end, a 3D printer was used to print a thin, aspherical surface onto a commercially available hemispherical lens made of glass. This significantly increases the optical quality while reducing the printing time and thus the cost factor.

To enable printing of larger lenses and further reduce printing time, the Extra Large Feature Print Set from Nanoscribe will be used. Here, a 5x lens with a writing field diameter of 3.2 mm is used in combination with a new, fast polymerizing material.

Benefit

• The larger writing field enables the production of optics with a single printing process, without the division into smaller printing units (stitching).
• Stitching seams, which reduce optical quality, can thus be avoided.
• Printing on larger lens blanks opens up new possibilities for combining with other optical elements.
• High-precision production of objects on the millimeter to centimeter scale has great potential for a wide range of applications, even outside the field of optics.
