High Sensitivity and Fast-Response Subminiature Detector with Built-in Preamplifier

摘要

Hamamatsu Photonics have developed a new InAsSb photovoltaic detector(P16702-011MN)with built-in preamplifier offering high sensitivity to mid-infrared light,up to 11 micrometers(urn)in wavelength.This was achieved by combining the latest InAsSb(indium arsenide antimonide)mid-infrared detector with the company's unique circuit design technology.Compared to Hamamatsu's previous detector modules with same level of sensitivity,the P16702-011 MN size and cost is drastically reduced,and it exhibits fast response time.Each molecule has its own vibration and absorbs infrared light at a specific wavelength determined by its energy.This property can be used to analyse and identify the type and quantity of chemical components contained in a sample.Therefore,mid-infrared light is widely utilised in the analysis of nitrogen oxides and sulphur oxides contained in exhaust gases from factories,etc.
