Spectrophotometers are used in many industries requiring precise colors. Whether we are talking about packaging, paints… this is the essential tool to ensure that the color produced consistently matches the color initially specified. Beyond precision, this clearly promotes waste reduction and saves time and money.
Spectrophotometers analyse the reflected wavelengths of visible polychromatic incident light. The reflected spectrum is measured at a large number of points, at small intervals, and it is compared to a database to deduce the color of the tooth. For an optical measurement, several million reference points are analysed on a tooth. These devices are currently the most precise and are not exposed to problems of aging of the light source.
Colorimeters and spectrophotometers are the two types of colorimetric measuring instruments used to capture, analyse, and communicate color. In the dental industry, it is needless to say that color accuracy (tooth shade) is important and it is clear that making a reliable colorimetric measurement is essential for the manufacture of a quality dental prosthesis.
However, there is confusion today among many users and healthcare professionals, arising from the lack of information provided by manufacturers. This is why we are going to answer your questions related to these two devices using two very distinct technologies: spectrophotometry and colorimetry.
It is a trichromatic colorimetric measurement tool that provides an objective assessment of color characteristics from light passing through the primary filters of red, green and blue. It simulates the way the human eye perceives color.
How does a colorimeter work?
The tooth is illuminated at an angle of 45 ° by an internal light source.
The light passes through the trichromatic filters, which indicate the amount of red, green and blue light reflected by the tooth.
The filter’s measurements are quantified in RGB values, which simulate the sensitivity of human eyes to light.
A spectrophotometer is a more complex colorimetric measuring instrument that takes into account light intensity as a parameter of color. It performs full-spectrum colorimetric measurement, as opposed to the trichromatic procedure of a colorimeter, and generates colorimetric data that is beyond observation by the human eye.
How does a spectrophotometer work?
An internal light source (On the Rayplicker, this source is represented by the ring of LEDs at the end of the measuring head) emits under different wavelengths so as to represent the entire visible color spectrum.
Each Led representing a specific wavelength of the spectrum emits one after the other in order to diffuse the light on the tooth.
Under each emission wavelength, the sensor measures the light intensity and absorbance of the tooth being analysed.
These collected data are then analysed by a comparison algorithm which compares the information collected with the spectral signatures of the various previously recorded shade guides.
The spectrophotometer displays this information in digital form.
