About Us

SUSS MicroOptics produces high-quality refractive and diffractive micro-optics for fiber coupling, collimation and beam homogenizing based on extensive experience in optical design, engineering, wafer-level manufacturing, metrology and packaging. SUSS MicroOptics is automotive qualified and key supplier for innovative photonic solutions in telecom, datacom, life science, laser, semiconductor equipment and automotive lighting.

SUSS MicroOptics SA was formed in 1999 with the remit to supply its parent SUSS MicroTec AG with micro-optical elements for their lithography equipment. As the market for micro-optics grew, SUSS MicroOptics expanded to meet the new and diverse requirements, developing its product portfolio and expertise to become one of the leading producers of precision refractive and diffractive micro-optics in the world.

SUSS MicroOptics is recognized by Carl Zeiss SMT GmbH as a Preferred Supplier and first became ISO 9001
in 2008. It is currently ISO 9001:2015 and IATF 16949:2016 certified. In 2013 it moved to its current premises, complete with state-of-the-art cleanroom, from where it continues to deliver excellence to its international customer base.

SUSS MicroOptics is a wholly owned subsidiary of SUSS MicroTec SE, a leading supplier of products and solutions for backend lithography, wafer bonding and photomask processing. For more information please visit www.suss.com.

Dr. Elmar Cullmann

Diploma in Physics at Würzburg University in 1971 and his PhD from the Technical University of Munich in 1977.

He has been with Karl Suss since 1977 where he developed diffraction-reducing exposure optics for proximity lithography. He introduced mid-UV and deep-UV systems and presented the first excimer laser exposure system in 1984.

After several years of development in x-ray lithography, he worked in high aspect ratio thick resist applications for MEMS/MST and bump / interconnect technology.

Dr. Elmar Cullmann was the chief scientist of SUSS MicroTec in Munich (FRG).
