Hamamatsu have developed a new InAsSb photovoltaic detector (the P16702-011MN) with built-in preamplifier offering high sensitivity to mid-infrared light, up to 11 μm in wavelength. This combines an InAsSb (indium arsenide antimonide) mid-infrared detector with new circuit design technology. Compared to previous detector modules with the same level of sensitivity, the P16702-011MN size and cost is drastically reduced, and it exhibits fast response time. This makes it an ideal choice for portable gas analysers able to immediately analyse exhaust gas components at measurement sites around factories.
