| titleOfInvention | Measuring device and measuring method for refractive index of optical material |
| abstract | The invention discloses a device and a method for measuring the refractive index of an optical material, belongs to the technical field of material performance testing, and can solve the problem that the refractive index of an optical material with high refractive index or tiny size is difficult to accurately measure by the existing refractive index measuring method. The device comprises a light source module, a transparent flat plate, an imaging module and a measuring module; the light source module is used for providing monochromatic light with preset wavelength; the transparent flat plate is provided with a first imaging reference mark; the imaging module is used for respectively carrying out optical imaging on the first imaging reference mark before and when the sample to be measured is measured; recording the imaging position of the imaging module before the sample to be measured is measured as a zero position; recording the imaging position of the imaging module when the sample to be measured is measured as an end point position; the measuring module is used for measuring the refractive index of the sample to be measured according to the displacement of the imaging module from the zero point position to the end point position and the thickness of the sample to be measured. The invention is used for measuring the refractive index of the optical material. |
