And even just the air in a clear sky blocks a huge range of the wavelengths of lights, pretty much only letting through visible light, anda smattering of infra-red and radio waves.
即便晴空万里光是空气就会挡住很大范围的光波波段，几乎只允许可见光、以及少数红外光和无线电波通过。
They support applications that require a broad wavelength range from UV to infra-red light, such as spectroscopy.
它们支持应用，需要在宽的波长范围从紫外到红外光，例如光谱学。
These include a camera, ultrasound, infra-red and thermal sensors, a range-finder sensor, a temperature sensor and ground detectors.
