Papenmeier is an owner-managed company with an international presence and market-leading products in rehabilitation technology and lumiglas (explosion-proof control systems). In addition, our in-depth industry expertise is integrated into our electronics and IT accessibility consulting services. The patented crescent-shaped Lumiglas luminaire, which combines lighting and a sight glass, provided innovative solutions to these challenges as early as 1960, laying the foundation for the Lumiglas division. Today, the extensive Lumiglas product portfolio covers the entire range of sight glass luminaires—explosion-proof and non-explosion-proof, halogen and LED—including various sight glass accessories, sight glass discs, and camera systems for use in potentially explosive atmospheres.
