The sun is a hot ball, it can radiate sublight. When the sun shines around the Atmosphere,  Before sun lights been absorbed by the atmosphere,  The range remarked in yellow shows a complete spectrum covering 200-2500nm,  After being absorbed by the atmosphere, only red remarked sunlight can shine on the earth. You see from 250 to 300, this range is absorbed by the ozone, however, it's reported.that ozone layers being damaged above the sky of south pole,  so that dangerous uv light shines directly on the earth, which could be a potential risk of skin cancer.

The earth sunlight energy come from solar radiation. And the sun energy shines on the atmosphere, and most sunlight will be absorbed by the atmosphere and only small portion of sunlight shine on the earth.

How are colorful colors being formed? With these questions in mind take us to introduce fieldspec spectroradiometer to you.

ATP9110 portable field spectroradiometer object spectrometer can measure raw data in real time, reflection, transmission radiation and irradiance spectrum curve.  This product uses fixed holographic grating and full-line array optical detector. This brings the characteristics of high sensitivity and high resolution, and avoids the possibility of instrument calibration failure caused by the use of built-in optical fiber splitting, narrow slits and moving gratings or prisms. The ATP9110 portable field spectroradiometer object spectrometer can achieve full spectral data collection in 100 milliseconds, reaching a collection rate of 10 times per second. Professional data acquisition software gives better play to the performance of the instrument and facilitates the subsequent processing of data.
