Smartphones are getting better with high-resolution cameras and slimmer designs. So, manufacturers need to carefully manage the height of camera lens modules. Even the smallest measurement errors can affect the image quality and performance of the smartphone camera.
Why Accurate Lens Module Height Matters
In smartphone manufacturing, camera lens modules use a mix of materials. These include glass, plastic, and metal. Each material has unique surface properties. Curved, stepped, or angled shapes make it hard to inspect lens module height accurately with traditional tools.
To meet these challenges, SinceVision’s SCI01045 Spectral Confocal Displacement Sensor offers a modern, highly accurate, and non-contact solution. This advanced sensor offers 0.006μm resolution and ±0.2μm linear accuracy. It works well with various materials and shapes. Plus, it has a high-speed sampling rate of 33kHz.
Inspection Requirements for Smartphone Camera Module Height
What Needs to Be Measured
The key measurement target in this application is the height of the smartphone camera lens module.
Inspection Challenges
The main challenge is ensuring the system works with various materials and shapes. This includes transparent lenses, reflective metal parts, and irregular surfaces.
Required Accuracy
The expected measurement accuracy is within 2μm. This is crucial for the smartphone camera's performance and reliability.
Advantages of Using SinceVision SCI01045 Spectral Confocal Displacement Sensor
a. High-Accuracy Height Measurement of Smartphone Lens Modules
The SinceVision SCI01045 sensor is designed for submicron-level measurement accuracy. With up to ±0.2μm linear accuracy and 0.006μm axial resolution, it can detect even the tiniest height differences. This is key for keeping the lens module height within strict size limits, especially in ultra-thin smartphone designs.
b. Reliable Measurement Across All Lens Materials
Unlike traditional sensors, SinceVision's sensor can work with a wide range of materials. Thanks to its custom-developed high-sensitivity algorithm and super-bright light source, it can measure:
1. High-transparency materials (like glass)
2. High-reflectivity surfaces (like metal)
3. Low-reflectivity or rough surfaces (like matte plastic)
This means the sensor delivers stable and repeatable results, no matter the surface type. It eliminates the common problems of poor signal return when measuring dark, shiny, or uneven lens materials.
c. Fast 33kHz Sampling for Real-Time Production Line Measurement
With a sampling rate of 33kHz, the SCI01045 can keep up with automated production lines. It captures data from fast-moving parts in real-time. It also tracks high-frequency vibrations. This way, it catches every detail, even when the smartphone lens modules move fast on the assembly line.
This cuts down missed inspections and speeds up production. It's great for high-volume smartphone manufacturing.
d. Wide ±45° Reflection Angle to Avoid Blind Spots
The sensor is designed with a ±45° light return angle, which helps it avoid blind spots and accurately scan the shape of curved or stepped lens modules. This wide-angle ensures that even complicated surfaces are measured correctly.
e. Easy Integration with Automation Systems
The SCI01045 works with RS232 and Ethernet. It also has analog and digital I/O. You can easily connect it to current factory automation and inspection systems. This makes adding it to any smartphone lens module production line simple.
Recommended Sensor for Smartphone Camera Manufacturing: SinceVision SCI01045
The SinceVision SCI01045 Spectral Confocal Displacement Sensor is the best choice for manufacturers who need:
1. Submicron-level lens height measurement accuracy
2. Fast, real-time inspection at 33kHz
3. Reliable performance across various materials
4. Support for curved or complex-shaped lens modules
By using this sensor, manufacturers can ensure that each smartphone camera module meets tight quality standards. This leads to better assembly precision, more stable products, and higher-quality smartphones for users.
