The joint history of Glas-Plus and Prinz Optics began in 1992. That was the year when Paul Hinz founded the company Opto-Chem Glas Coating, which specialised in glass coating and is today known as Prinz Optics GmbH, in Stromberg, Germany. Having previously headed the “Surfaces Development” department at the manufacturers of specialist glass Schott in Mainz, Germany, Paul Hinz was therefore already a proven expert in this technology.

Increasing demand for coated lighting fixtures prompted Paul Hinz to establish the company Glas-Plus Beschichtungs GmbH & Co. KG in 1995, which particularly focused on automotive lighting. In the years that followed, Glas Plus developed and manufactured top quality coated lamps which were able to achieve the desired colour temperature in car headlights. The company also began focusing on custom-made glass coatings with optical and electrical functions, as well as metal coatings with a catalytic function.

Until 2022, Paul Hinz managed Glas-Plus together with his partner Peter Röhlen, who was responsible for process development for dip coating at Schott. Peter Röhlen has been the sole Managing Director since mid-2022.

Peter Röhlen, owner and managing director of Prinz Optics GmbH, which specializes in dichroic glass coating of surfaces for design / architecture, lighting and industry, took over the management of Glas Plus Beschichtungs GmbH & Co. KG in 2011. Thanks to this personal union, Glas Plus and Prinz Optics are now closely intertwined.

Due to the extensive collaboration between the two companies, they are able to offer clients a comprehensive range of services in the field of glass coating.
