I. Customer Pain Points

Have you ever wondered how a smartphone achieves tight dustproofing and daily water resistance?Beyond sealing gaskets, the key lies in the micron-level gap between the screen and the frame — almost invisible to the naked eye.A slightly wider gap allows dust and moisture to penetrate easily; a narrower one may cause squeezing and screen damage.Traditional contact probes risk scratching the screen or metal frame and struggle with compatibility across various materials.How can we achieve accurate, non-destructive measurement?

II. Solution

Take the Shenshi Intelligent confocal chromatic displacement sensor SCI01045 as an example.It performs scanning via a light beam at a working distance of 10 mm, with a minimum spot diameter of only 7.1 μm.It can quickly capture profile data along the path from the frame to the screen, and the software calculates and outputs the gap width with linear accuracy up to ±0.2 μm.

As shown above, this is the profile curve generated from actual measurement.

The strength of the Shenshi Intelligent SCI01045 confocal chromatic displacement sensor is:it works for metals, glass, and plastics without sensor replacement;it resists reflection and scratching, and can even measure transparent layers thicker than 30 μm.This enables high-speed, high-precision gap inspection on production lines, greatly improving product yield and driving automation upgrades.

Core Advantages
