I. Pain Points in Mobile Phone Lens Thickness Measurement

Problem: Mobile phone lenses usually consist of multiple stacked lenses, and each lens surface is coated with films of various colors.

Challenge: Traditional measuring tools struggle to accurately locate the thickness of each layer and are easily disturbed by colors, resulting in distorted data.

II. Shenshi Intelligent's Solution

Shenshi Intelligent point-spectrum confocal chromatic displacement sensors are designed to solve these industry pain points.Centered on advanced optical technology, they redefine the standard of precision measurement and serve as the "precision ruler" for high-end optical manufacturing such as mobile phone lenses and VR/AR optical engines.

01 Multi-layer Penetration Capability like "X-ray Vision"

Adopts confocal chromatic technology to realize penetrating precision measurement of multi-layer lenses.0.006 μm resolution accurately captures tiny thickness variations.

02 "Color Recognition" Intelligent Algorithm

Equipped with white-light point source and self-developed spectral decomposition algorithm, it automatically identifies color characteristics of lenses, dynamically adjusts spectral weight according to optical properties of different materials, stabilizes surface signals, and ensures reliable measurement data.

03 "Anti-interference" Industrial-grade Design

• Micron-level spot: 12 μm spot diameter for accurate measurement at critical positions such as lens edges and curved apexes.

• Wide-angle receiving structure: ±25° light-receiving angle effectively suppresses stray light interference from glue splashes and dust reflection in production environments.

• High-speed sampling: 33 kHz sampling rate records micron-level surface changes in real time and reduces missed detection risks.

III. Application Value

01 Improve Yield Rate

Accurate thickness measurement with tighter tolerances effectively reduces imaging issues caused by thickness errors.

02 Lower Inspection Cost

A single sensor can inspect multi-layer lenses simultaneously, reducing equipment investment and manual intervention while optimizing production flow.

03 Adapt to High-speed Production Lines

Non-contact measurement and high-speed sampling perfectly match the rhythm of modern high-speed production lines.
