Opto Diode Corporation, an ITW company, presents the BXT2-17TF, a single-channel, infrared (IR) detector with an integrated 4.67 µm optical bandpass silicon filter. The high-performance lead selenide (PbSe) cooled device provides excellent sensitivity for industrial carbon monoxide (CO) detection in harsh environments.

Image-processing in the near infrared spectrum is already well established in the photovoltaic industry where it is used in demanding optical inspection procedures that check solar cells for micro-cracks, which can occur during crystal growth and wafer sawing. But this technology has much more to offer and it is gaining in importance in other areas, as this article shows.
