Abstract

The invention relates to the technical field of optical measurement, and discloses refractive index measurement equipment and a refractive index measurement method and device. The refractive index measurement range of the refractive index measurement equipment is adjustable, and thus the measurement application range is widened. The refractive index measurement equipment comprises a magnetic field generation device generating an adjustable magnetic field, a shell, a light transmitter, a light receiver, a sample to be measured and a control processor, wherein the shell is located in the magnetic field generated by the magnetic field generation device and is filled with magnetofluid, the light transmitter, the light receiver and the sample to be measured are immersed in the magnetofluid, and the control processor is connected with the magnetic generation device and the light receiver. The light transmitter is used for transmitting light towards the sample to be measured, the light receiver is used for receiving light reflected by the sample to be measured, and the included angle of the reflected light and the incident light is a set included angle; the control processor is used for judging whether total reflection can happen, determining the refractive index of the magnetofluid according to the critical magnetic field intensity in total reflection and determining the refractive index of the sample to be measured according to the refractive index of the magnetofluid and the set included angle.

Description

technical field [0001] The invention relates to the technical field of optical measurement, in particular to a refractive index measurement device, a refractive index measurement method and a device. Background technique [0002] Optical enhancement film and optical lens are the basic devices in the field of optics, and their application fields are very wide, including: microscopes, cameras, exposure machines, mobile phones and display devices, etc. The indicators to measure the quality of optical films and optical lenses should include film thickness, curvature, refractive index, reflectivity, absorption rate, etc. Among them, the refractive index is one of the most important parameters to characterize the optical properties of optical films and optical lenses, and the measurement of the refractive index is an important link in process control and quality control. [0003] The existing methods for measuring the refractive index include total reflection critical angle measu...
