Abstract

The invention discloses a device for measuring the color, brightness and reflectance spectrum of glass at different angles. The wide-spectrum light emitted by a wide-spectrum light source is guided into a first lens through an optical system to correct it as parallel light, and the light is corrected as parallel light at a temperature greater than 0 degrees and less than 90 degrees. degree of inclination to the surface of the glass sample, reflected by the upper and lower surfaces of the glass sample to form two beams of reflected light that are focused by the second lens. The reflected light is mixed and diffused by the light diffusion device and then connected to the spectrum analysis device through another optical system. The spectrum analysis device is connected to the computer through the data line. This glass color measurement device has the characteristics of simple structure, fast measurement speed and accurate measurement. , the reliability of the device is very high, and the signal acquisition speed is also very high, so it can also be used for online measurement.

Description

technical field [0001] The invention relates to a measuring device, in particular to a device for measuring the color, brightness and reflectance spectra of glass at different angles. Background technique [0002] The glass color, reflective brightness and wide-spectrum reflectance tests are generally tested with a vertical glass surface, and the coating process is monitored by using the measured color and other information. With the increase in the number of film layers, the existing glass measurement devices cannot meet the above requirements. Measurement requirements, when the number of coating layers reaches 10 or more, sometimes even if the color and brightness measured vertically to the glass surface can meet the process or product requirements, but at other angles, the glass may show different colors. It is necessary to monitor the coating process by observing the color and brightness of the glass at different angles to increase the stability of the coating process. ...
