GaN sort UV sensors „KPDU086SU27-H11Q and KPDU086SU31-H11Q“ obtain excessive sensitivity to UV-B and UV-C deep ultraviolet ray
TOKYO–(BUSINESS WIRE)–Kyoto Semiconductor Co., Ltd. (President and CEO Yoshihisa Shinya, Head workplace: Fushimi-ku, Kyoto metropolis), a number one optical gadget resolution producer with world-class applied sciences and Japanese high quality, has introduced two merchandise of GaN*1 UV sensor; „KPDU086SU27-H11Q and KPDU086SU31-H11Q“.
The UV sensors „KPDU086SU27-H11Q“ and „KPDU086SU31-H11Q“ have been developed with the goal of attaining greater sensitivity than standard Si*2 sort UV sensors to fulfill the wants of the deep UV*3 sensing market.
Since standard Si-type UV sensors detect a variety of wavelengths, it’s common to use a filter to restrict the sensitivity to the UV wavelength vary. The quantity of sunshine was attenuated by passing by means of the filter.
The newly developed KPDU086SU27-H11Q and KPDU086SU31-H11Q use GaN to allow direct gentle reception on the gentle receiving a part of the sensor with out utilizing a filter as GaN has sensitivity to a particular wavelength vary of ultraviolet gentle. It’s now potential to acquire roughly 3 times as excessive sensitivity as Si-type UV sensors. *4
As well as, the merchandise have sensitivity within the wavelength vary restricted to UV-B*5 and UV-C*6, that are in excessive demand amongst ultraviolet rays.
The brand new merchandise can be utilized to watch the ultraviolet gentle depth of germicidal lamps in meals factories, medical establishments, and water purification-related establishments, and to watch the sunshine depth of ozone detection gentle sources.
The mass manufacturing of the GaN UV sensors „KPDU086SU27-H11Q and KPDU086SU31-H11Q“ are scheduled to start out on April 28, 2023.
*1 GaN: Gallium nitride a sort of semiconductor
*2 Si: Silicon, a sort of semiconductor
*3 Deep ultraviolet rays: UV rays within the emission wavelength vary of λ = 200-300 nm. UV-B and UV-C are stated to be deep UV rays.
*4 Comparability between KPDU086SU27-H11Q and our Si UV sensor KPDU400F-2
