Jenoptik Expands Optics Manufacturing at Jena Campus
Jenoptik revealed plans to expand a high-end manufacturing facility for semiconductor optics at its production campus in Jena. The company said it will invest a sum in the low double-digit million-euro range starting at the end of the year.

Preliminary planning on the expanded production areas is expected to be completed by the end of the year. Once approvals and contracts have been granted, the renovation of the currently vacant hall is expected to begin next year. The site is scheduled to begin production in the second half of 2027.
Jenoptik said that, depending on medium-term growth, particularly with semiconductor equipment customers, as well as global manufacturing trends, the company may consider an additional expansion.
In addition to its investment in the facility’s expansion, Jenoptik plans to invest in state-of-the-art machinery and infrastructure for the site.
Jenoptik opened a micro-optics fabrication site in Dresden earlier this year.

Glossary
- semiconductor
- A semiconductor is a type of material that has electrical conductivity between that of a conductor and an insulator. In other words, semiconductors have properties that are intermediate between metals (good conductors of electricity) and insulators (poor conductors of electricity). The conductivity of a semiconductor can be controlled and modified by factors such as temperature, impurities, or an applied electric field.
The most common semiconductors are crystalline solids, and they are...
