This paper proposes a new general design scheme about the digital system measuring refractive index. It is based on CCD machine vision alignment technique. This system is mainly composed of auto-collimator, transmission mechanism, locking and trimming mechanism, and incremental encoder goniometer institution. First of all, to meet the demand in a wide spectrum of various aberrations, the auto-collimated optical system is designed, which achieve a good image quality. Secondly, the spiral trimming mechanism is designed, and in accordance with the micros-tress assembling method the locking mechanism is achieved. The out shaft of photoelectric encoder can move slowly and steadily, and ensure its position more precise adjustment. Finally, the detection error is analyzed based on the principle of correction formulas to consider the influence of air refractive index. The experimental results show that the system can measure the refractive index of transparent material such as glass, and the accuracy of refractive index detection is up to ±3×10-6.
