Description

Technical Field

[0001] The invention relates to the technical field of sun photometers, in particular to a winding prevention protection device for sun photometer rotation. Background Art

[0002] Sunphotometers are primarily used to measure the radiant brightness of the sun and sky in different visible and near-infrared wavelengths, directions, and time periods to estimate the characteristics of atmospheric components such as aerosols, water vapor, and ozone.
