I. Project Background

Flatness is a key indicator for measuring surface shape deviations of transparent glass.Repeatability testing ensures that the flatness of each batch and each piece of glass meets established standards and requirements, reducing quality problems caused by uneven flatness.

During production, fluctuations in glass flatness may occur due to materials, processes, equipment, and other factors.Repeatability testing allows timely detection and correction of such variations, guaranteeing stable and consistent product quality.

Shenshi Intelligent confocal chromatic displacement sensors adopt non-contact measurement, avoiding scratches and wear caused by traditional contact methods.This protects the surface of transparent glass, improves measurement accuracy and reliability, and enhances both production efficiency and product quality.

II. Inspection Requirements

• Object under test: Transparent glass

• Measurement item: Flatness repeatability

• Required accuracy: 0.002 mm

III. Vision System Solution

Shenshi Intelligent confocal chromatic displacement sensors perform non-contact measurement to protect transparent glass from scratches.By scanning flatness values at 9 measurement points on the workpiece surface, data is collected in one pass and analyzed by professional measurement software, enabling real-time acquisition of surface data.

IV. Product Advantages

• Nanometer-level precision: Equipped with customized scientific-grade CMOS, the sensor delivers stable nanometer-level accuracy, precisely capturing and recording tiny changes in glass flatness.

• Large-angle measurement range: Mirror measurement angle up to ±60°, easily handling highly curved or inclined transparent glass surfaces.

• Non-contact measurement: Protects glass surface quality and improves product yield.

• Universal material compatibility: ABLE automatic brightness adjustment effectively optimizes high-gloss sensitivity and automatically adapts laser brightness to different reflectivity levels.

• Rich communication interfaces: Supports integration with other measuring equipment and control systems for automated measurement and data transmission.
