Safe compound detects mid-infrared light to a wavelength of 14.3μm
By utilising compound opto-semiconductor manufacturing technology developed in-house over many years Hamamatsu Photonics has succeed in mass-producing a compound opto-semiconductor (type-II superlattice infrared detector) not containing harmful mercury (Hg) and cadmium (Cd) but able to detect mid-infrared light to a wavelength of 14.3μm.
Mercury and cadmium are common materials used for mid-infrared detectors but are restricted substances under the RoHS directive issued by EU (European Union) that prohibits use of certain hazardous substances in electrical and electronic products sold in the EU market.
Hamamatsu Photonics expects the new product will likely replace currently available mid-infrared detectors that contain restricted substances, and will prove well suited for analytical instruments that rely on mid-infrared light to identify substances contained in the air, foods, and drugs. Hamamatsu will begin selling this new product to domestic and overseas analytical instrument manufacturers on September 2nd, 2019.
