[0041] The present invention will be further explained below in conjunction with the drawings and embodiments.
[0042] As attached Figure 1~3 As shown, a silicon photocell-based automatic polarimeter with no Raday modulator includes a light source 1, and an achromatic condenser lens 2 is installed on the exit light path of the light source 1, and the light is emitted through the achromatic condenser lens 2. Into the polarizer 3, the sample tube 4 is installed on the exit light path of the polarizer 3, the incident end of the sample tube 4 is installed with an interference filter 5, the light passes through the sample in the sample tube 4 and then enters the analyzer assembly 6. The silicon photocell assembly 7 is installed on the exit light path of the analyzer assembly 6;
[0043] A glass sheet 8 is mounted on the light opening of the analyzer assembly 6, and at least two polarizers 9, 9'which are perpendicular to the polarization direction are closely mounted on the glass shee...
