Infrared-permeable glass-ceramic: NEXTREMA® translucent bluegrey (712-6)

The material type translucent bluegrey offers countless possibilities for engineers and designers in the IR range. This NEXTREMA® type boasts more than outstanding infrared wave transmission. It also scores highly with its dead-front lighting effect. I.e. when viewed from the top, none of the parts installed below are visible, yet the light still shines from below. This premium material impresses with its unique material properties – even when subjected to severe mechanical, thermal or chemical stresses. Last but not least, this translucent, bluegrey glass-ceramic serves as a visual highlight for industrial and product design.
