Japan Dowa Developed 1300 Nm Band Near-infrared Chip

- Sep 19, 2018-

According to foreign media reports, Japan's Dowa Electronics Corporation said recently that it has developed a 1300 nm band of near infrared chips. Dowa said that the size of the new chip is 3.5 times the size of the previous model, and its output power is 6.8 mW. It is said that Dowa has begun to provide samples for the new chip.——LED chip


It is noteworthy that various optical sensors using LED have the advantages of small size, power saving and long service life. In addition, near-infrared light with wavelengths ranging from 800 nm to 2000 nm can be highly permeable to organisms used in optical sensor applications, including crop and food analysis, as well as health and medical applications. Dowa expects that the near infrared LED market will continue to expand in the medical field. For example, near infrared LED can be used to measure blood sugar without sensors for blood sampling.——LED chip


Dowa claims that its newly developed near-infrared LED chip with a central wavelength of 1300 nm greatly increases the light output to the top surface, which is necessary for sensor applications; meanwhile, near-infrared LEDs achieve high power output.——LED chip


Dowa plans to further expand these technologies by producing near-infrared LEDs with center wavelengths of 1 450 nm and 1 650 nm in the future, thereby further improving its near-infrared emitter lineup.——LED chip
