The homogenization of smart phones has always been one of the biggest problems facing the entire industry, since Jobs changed the life of the mobile phone with the iPhone, it seems that all mobile phones have the same appearance overnight, and occasionally some "different" are quickly drowned.

In fact, in order to ensure the accuracy of each measurement result, almost all measuring equipment or systems need to be calibrated before use. Although the measuring equipment and system have gone through a rigorous calibration process before leaving the factory, this is not once and for all, with the change of temperature, humidity, vibration and light and other factors in the use environment, the measuring equipment and system may be interfered with, and the measurement accuracy will be greatly affected. When using a spectral confocal measuring device or system, a calibration process should be carried out in order to ensure measurement accuracy. The following Shenzhen Liyi will introduce the calibration method of spectral confocal sensor in detail with you:

What is the principle of spectral confocal measurement? Many people may be unfamiliar with the term, spectral confocal is actually a sensor.

What are the advantages of the principle of spectral confocal displacement sensor? Spectral confocal displacement sensor is actually a device that establishes the correspondence between distance and wavelength through the optical dispersion principle, and uses the spectrometer to decode the spectral information to obtain the position information. So what are the advantages? Shenzhen Liyi spectral confocal displacement sensor manufacturers Share:

What are the two measurement modes of spectral confocal? By analyzing the focusing position of different wavelengths of light on a specific surface, spectral confocal measurement technology can achieve high precision dimensional measurement and microscopic morphology analysis.

Shenzhen Liyi Technology spectral confocal manufacturers to tell you about the spectral confocal (fiber coaxial displacement/color laser displacement) controller name and parameters: Using multiple prism dispersion components, the light energy utilization is more than 2 times higher than other dispersion principles. Linearity is more than 2 times higher. K-type double shell double damping structure, the spectrum module shell is made of a whole piece of metal hollow-out, good rigidity and stability, greatly reducing the impact of vibration and external heat conduction when the machine is working, reducing the sensor vibration damage or misalignment when the machine is transported, electromagnetic shielding performance is good, good heat dissipation. Modular LED light source. Saving controller with multi-channel version reduces cost, synchronization time error between channels is less than 1ns!
