使用不同的红外探测器和不同的光学元件(滤光片、透镜),可以使红外测温仪表有不同的工作波段范围。譬如,用硅光电池(其响应波段为0.4～1.1μm)作探测器,同时配用透过大于0.8μm波长的干涉膜滤光片,用光学玻璃作透镜材料,这时的测温仪表便可以有0.8～1.1μm的工作波段范围。 实践证明:根据被测对象的特性及测温现场的环境,正确选择不同工作波段范围, Using different infrared detectors and different optical components (filters, lenses), you can make the infrared thermometer have a different working band range. For example, the use of silicon solar cells (the response wavelength range of 0.4 ~ 1.1μm) as a detector, with the use of more than 0.8μm wavelength through the interference filter, the optical glass lens material, then the thermometer can There is 0.8 ~ 1.1μm working band range. Practice has proved: According to the characteristics of the measured object and the temperature field environment, the correct choice of different working band range,
