From Konica Minolta Sensing Americas, Inc.
Resins used as restorative materials for dental treatment to fill drilled teeth or cap ground teeth have made remarkable progress in recent years. However, the problem that the surface of the resin is easily stained by tobacco or food has still not been solved. Because of this, this college laboratory conducts research on improving the resin surface condition. To improve the resistance of the resin to pigmentary deposits, attention is being paid to surface treatment agents which improve the water repellency and the possibility of using various surface treatment agents is investigated. For this investigation, the color of the sample requires quantification with a colorimeter which can measure the samples (10mm) accurately and provide numerical data. Surface treatment agents are also receiving attention for use on industrial parts. A sample treated with a surface treatment agent and an untreated sample are both soaked in tobacco solution. Then the color differences from a sample soaked in distilled water are measured using Colorimeter. Products & Services
Color and appearance instruments are used to measure the properties of paints and coatings including color, gloss, haze and transparency.
Color sensors register items by contrast, true color, or translucent index. True color sensors are based on one of the color models, most commonly the RGB model (red, green, blue).
Dimensional and profile scanners gather two-dimensional (2D) or three-dimensional (3D) information about an object.
