Heraeus‐pioneer in xenon arc light exposure technology and modular test cabinet design

Heraeus is a name synonymous with testing, particularly sunlight and weather exposure testing. Light testing equipment was a logical development for the smelting and engineering firm founded in Hanau, Germany, in 1851, which produced the first high purity quartz glass at the turn of the century. The development of quartz lamps led, at first, to the production of artificial sunlight lamps for medical purposes.
