You can tow up to four. But the sampling frequency will be reduced.

The company provides measured data, most of which are within 1um, and can achieve tens of nanometers.

Temperature drift, fixture installation, equipment vibration, etc. will affect the measurement results, it is recommended to set the time calibration, eliminate this factor to improve data stability.

How does the spectral confocal sensor measure the glue height? At present, when the mobile phone center plate and screen module are fitted, it is necessary to point a circle of transparent UV glue on the center plate.

With the development of confocal spectroscopy technology, we can see the measurement of almost all types of materials, flatness, camboid, height difference, grooves, etc., applied to 2.5D/3D curved glass and other mobile phone 3C industry. 光谱共焦测量方法恰恰利用这种物理现象的特点。光谱共焦测量技术通过分析不同波长的光在特定表面的聚焦位置以进行高精度的尺寸测量和微观形貌分析。根据这一测量原理，特定波长的光可能聚焦在样品正面，而对于透明材质样品，两条不同波长的光在样品的正反面聚焦。这正是光谱共焦提供的两种测量模式，前者为位移测量模式，后者为厚度测量模式。今天我们与立仪科技公司一起来看看光谱共焦测量的方法：

As we all know, the current "made in China" is constantly transforming and upgrading to "China's intelligent manufacturing", while the labor cost is getting higher and higher, China's manufacturing machine to replace the artificial has been the general trend, in the trend of The Times and the inevitability of development, machine vision technology has become the focus of attention, but also a major breakthrough point in the future of manufacturing upgrading.
