Method and instrument for measuring and displaying optical characteristics of diamond

Abstract

The invention discloses a method for measuring and displaying optical characteristics of a diamond, and relates to the technical field of optical characteristicmeasurement of diamonds. The technical scheme is that the method comprises the following specific operation steps: S1, carrying out ultrasonic cleaning on a measured diamond, then putting the diamond on a jewelry scale for weighing, and recording a weighing result; S2, lightly taking and placing the diamond weighed in S1 on the surface of a sleeve at the top of a moving platform through dust-free tweezers, and after a sensitive spring is stressed, enabling the sleeve to shrinks downward, so that the diamond is stabilized at the top of the sleeve; and S3, driving a first servo motor to rotate, and enabling a gear to be meshed with teeth .A servo motor III is driven to rotate, therefore, the direction of the diamond can be conveniently rotated according to the measurement requirement, and the comprehensiveness of diamond detection is improved; and meanwhile, the position of the objective table on the top of the base is moved in cooperation with the moving platform, so that the detection progress is conveniently improved, the detection error caused by the detection environment is reduced, and the detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of measuring diamond optical properties, in particular to a method and an instrument for measuring and displaying diamond optical properties. Background technique [0002] Diamond refers to polished diamond. Diamond is a natural mineral and the original stone of diamond. Simply speaking, diamond is a simple crystal composed of carbon element formed under the conditions of high pressure and high temperature deep in the earth. It is generally believed that diamonds are It is crystal clear. In fact, most diamonds contain tiny inclusions. They are the result of the variation of the surrounding environment and the invasion of other crystals during the development and crystallization of diamonds. The quality of diamonds generally depends on the weight, cut, and Clarity and other dimensions are identified to determine the value of the diamond. [0003] There are following deficiencies in the prior art: the existin...

Problems solved by technology

[0003] There are following deficiencies in the prior art: the existing diamond optical measurement instruments generally cannot ensure that diamonds are tested in multiple directions and angles on a stable table. Optical detection, which leads to deviations in the detection results, and cannot accurately measure diamonds optically
