Hamamatsu Photonics is the First in the World to Succeed in Mass-Producing a Compound Opto-semiconductor

Detecting mid-infrared light to a wavelength of 14.3 μm without using hazardous substances restricted under the RoHS directive. Sales of this new compound opto-semiconductor begins September 2, 2019


By utilizing compound opto-semiconductor manufacturing technology developed in-house over many years, we are the first in the world to succeed in mass-producing a compound opto-semiconductor (type-II superlattice infrared detector*1) not containing harmful mercury (Hg) and cadmium (Cd) but able to detect mid-infrared light to a wavelength of 14.3 micrometers (a micrometer, abbreviated μm, is one millionth of a meter). 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. Our new product will likely replace currently available mid-infrared detectors that contain restricted substances, and will prove ideal 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 2, 2019.

Our new product will be on display at the JASIS 2019 exhibition held in Makuhari Messe (Mihama-ku, Chiba-city, Japan) for 3 days from September 4 (Wed) to 6 (Fri). This is Asia’s largest exhibition in analytical and scientific instrument applications.

*1: Type-II superlattice infrared detector is a compound opto-semiconductor with a unique structure composed of thin films of two different materials alternately laminated on a substrate to form a photosensitive layer.

We, the members of Hamamatsu, consider ourselves a research and development company. As a company, we believe that the only way to achieve sustainable growth is to maintain our technological advantages. It is our job and passion to advance photonic technologies. Hamamatsu has been working with the Photon for more than 50 years. We have established ourselves as the top company of photoelectron conversion technologies in the world. However, we have yet to fully grasp the nature of the Photon and its potential. The more you study, the more you realise how little you know about the Photon and its applications. That is why we continue to move ahead vigorously with basic research and apply what we learn to photonics. We realise that pursuing the knowledge of photonics technologies alone, by ourselves, is like reaching for the stars with a ladder. Thus we will work together with colleagues around the world, be they researchers, customers or stockholders, who share our passion and the belief that understanding photonic technologies will lead to broader applications and also generate new industries for the advancement of humankind.
