Thermopile detector


High sensitivity, built-in thermistor


The T15962-01 is a high-sensitivity thermopile detector suitable for radiation thermometers. Silicon is used for the window material and light with a wide range of wavelengths (1.1 µm to far infrared light) can be transmitted, so the T15962-01 can measure the amount of infrared light generated by the measurement target. This product comes with a built-in thermistor, so it can correct sensitivity changes caused by changes in ambient temperature.
