Small Optics for Major Pocessing Tasks

Robust in continuous operation

The processing optics of the OTC series are specifically designed for usage in a demanding industrial environment. Because of its robust design, the OTC series can also prove itself in permanent operation by its high reliability and longevity. The integration of an innovative cooling system provides an efficient heat dissipation and allows for usage even in difficult process conditions.
Our experience with high-power diode lasers and our far more extensive knowledge of their applications have influenced the construction of the OTC optics series. The result is an optics series that is ideally tailored for our diode lasers, which is at the same time optimized for welding and cladding applications.

Compact and flexible 

The compact design of the OTC processing optics allows for an easy and tremendously flexible integration with systems that are quite different. The cooling system of the optics and the optional sensor package are completely integrated into the processing optics and do not require additional assembly space. Because of its monolithic construction and a consistent avoidance of interfaces within the optics, the OTC series can prove itself with its high reliability and low weight. 
Specifically designed for highly dynamic applications, and for usage in small handling systems or for integration into systems with low assembly space, the OTC series offers excellent features.

Analysis in real time

With the available sensor package, you can keep an eye on the condition of the optics at any time. Sensors that are integrated for monitoring deliver your data directly to the laser control, thereby allowing for a central evaluation and visualization. Furthermore, the intelligent optics offer via additional digital services a decentralized and subordinated condition monitoring. In this way, you can constantly check the most important function values.

Tailored designs 

To be able to use the advantages of the monolithic design and meet thereby the most divers process demands of our customers, the OTC processing optics is available in three different designs. Each can be flexibly configured with regard to focal lengths and additional components. Version OTC-3 B2 can even fit into the tightest of spaces with dimensions of 173 x 60 x 60 mm.
To connect cameras or sensors, versions OTC-3 S2 and OTC-3 A2 offer interfaces that allow for a coaxial process observation. Here, version OTC-3 A2 additionally has a 90° deflection of the laser beam. An LLK-D fiber connector holder and a quick-change protection glass are part and parcel of the standard equipment in all versions.
