Core offering

sglux GmbH develops, manufactures, and distributes silicon-carbide (SiC) based UV photodiodes, integrated TOCON photodiodes with built-in amplifiers, UV sensor probes, UV radiometers, and supporting signal transducers for industrial UV measurement applications. The company also provides PTB-traceable calibration services and customized sensor solutions built on a modular hardware platform.

Product overview

sglux GmbH offers a modular UV measurement product portfolio centered on Silicon Carbide (SiC) photodiode technology. The product line ranges from foundational SiC photodiode chips and wafers through integrated TOCONs (photodiodes with built-in amplifiers) to complete UV sensors, radiometers, and turnkey measurement systems. Supporting products include transducers (VOLTCON, AMPCON, Digiboard, Multiboard) that convert photodiode signals to standard industrial outputs (0-5V, 4-20mA, frequency), as well as the SGCD4 digital photocurrent digitizer. The company provides calibration services traceable to PTB standards and offers customized sensor configurations for specialized applications. In 2026, sglux expanded into InGaP photodiodes for applications where SiC's visible blindness is a limitation.
