Instrument characteristics

The high stability semiconductor laser is used as the light source, which effectively solves the errors caused by the fluctuation of light intensity and the change of polarization state in the measurement process. In the power measurement range, the use of adjustable range is beneficial to eliminate the shift error, and the adjustable range has unique advantages in relative light intensity measurement, such as power change measurement, light intensity distribution measurement and other experiments
