This text introduces a set of new-style multi-wavelength solarphotometer contolled by siglechip (SCM). The autocontrol system of this instrument was improved based on the proto- type devoloped by ourself. The new-style photometer is portable and can accornmodate to the abominable environment, miniaturize and improve the ratio of his performance and price. Here are described the necessity of improving solorphotometer, design project, instrument structure, performance index, software design, instrument calibration and its application.
