In precision manufacturing, electronic inspection, lithium battery, photovoltaic, and other industrial fields, line scan industrial lenses serve as the core compatible components for line scan cameras, directly determining inspection accuracy, field of view, and imaging efficiency. POMEAS offers three line scan lens series—4K, 8K, and 16K—tailored to varying precision requirements. Each series is compatible with corresponding 4K/8K/16K line scan cameras, delivering resolutions spanning the high-precision range of 5μm to 7μm.

I. Three Major Line-Scan Lens Series

1. The 4K line scan lens series is compatible with 4K line scan cameras (4096 horizontal pixels), offering a resolution as high as 7μm. The field of view ranges from 10mm to 500mm depending on the working distance, supporting frame rates ≤60fps and distortion ≤0.1% (low distortion design).

Core Advantages:

• High Cost-Effectiveness: Balances detection performance and cost for medium-precision applications, ideal for mass production scenarios.

• Wide Field-of-View Compatibility: Supports inspection needs ranging from small-to-medium components (e.g., electronic parts) to large-format items (e.g., printed rolls).

• Low Light Loss Design: Utilizes high-transmittance optical glass to maintain imaging clarity in low-light environments, adapting to diverse industrial lighting conditions.

• Typical Applications: Label registration accuracy inspection in printing and packaging; initial defect screening of PCB board appearance in electronics; fabric texture quality screening in textiles.

2. The 8K line scan lens series is compatible with 8K line scan cameras (horizontal pixels: 8192), offering resolutions up to 7μm (select models support 5.5μm). With a field of view ranging from 5mm to 300mm, it supports frame rates ≤80fps, distortion rate ≤0.08%, and a 20% improvement in optical contrast (compared to the 4K series).

Core Advantages:

• Balancing Precision and Efficiency: Enhances pixel density beyond 4K while maintaining detection accuracy and data processing speed, preventing frame rate loss associated with high resolution.

• Superior Detail Capture: Delivers clearer imaging details for minute defects such as deformed electronic component pins and micro-scratches on lithium electrode sheets.

• Wide Compatibility Interface: Supports multiple camera interfaces including C-mount and F-mount, compatible with mainstream 8K line scan cameras.​

• Typical Applications: Lithium battery electrode coating thickness inspection, semiconductor chip lead appearance inspection, photovoltaic cell busbar defect detection.

3. The 16K line scan lens series is compatible with 16K line scan cameras (16,384 horizontal pixels), offering a resolution of up to 5μm. It provides a field of view ranging from 3mm to 200mm, supports frame rates ≤100fps, and maintains a distortion rate ≤0.05%. The lenses utilize ultra-low dispersion glass to minimize chromatic aberration.

Core Advantages:

• Ultra-High Precision: Industrial-grade 5μm resolution meets micron-level defect detection requirements, making it the core choice for high-precision scenarios.

• Exceptional Imaging Stability: Ultra-low dispersion and low distortion design ensure high imaging consistency during long-term inspection, reducing misjudgment rates.

• High-Speed Adaptability: Supports high-frame-rate line-scan cameras, compatible with high-speed production lines (e.g., rapid semiconductor wafer inspection, continuous screening of precision hardware components).

• Typical Applications:Wafer scratch detection in the semiconductor industry、Micro-part dimensional measurement in precision hardware manufacturing、High-precision component appearance inspection in medical equipment manufacturing.

II. Model Selection Guide: Three Steps to Find the Right Fit

Step 1: Define the precision requirements 

• For inspection requirements of “Defect Detection ≥7μm” (e.g., printing misregistration, fabric texture defects): Prioritize the 4K line scan lens series for superior cost-effectiveness.

• For defect detection requirements of “5.5-7μm” (e.g., micro-scratches on electrode sheets, chip pin deformation): Select the 8K line scan lens series for balanced precision and efficiency.

• For defect detection requirements of “≤5μm” (e.g., wafer scratches, micro-component dimensions): The 16K line scan lens series is essential to meet ultra-high precision standards.

Step 2: Combine the dimensions of the object being measured with the production line speed.

• For large test objects (e.g., wide rolls >300mm): Prioritize the 4K series for a more suitable field of view.

• For medium-sized test objects (100-300mm): The 8K series balances field of view and accuracy.

• For small test objects (<100mm): The 16K series' small field of view and high precision are more suitable.

• High production line speed (>80fps): The 16K series supports high frame rates to prevent imaging ghosting. Medium speed (60-80fps): The 8K series offers superior adaptability.

Step 3: Consider Industry-Specific Scenarios

• Batch inspection scenarios in electronics, printing, textiles, etc.: The 4K series reduces costs and is suitable for large-scale deployment.

• Lithium battery / photovoltaic and other medium-to-high precision applications: The 8K series meets mainstream inspection requirements with strong compatibility.

• Ultra-high precision applications such as semiconductors and medical imaging: The 16K series' low dispersion and low distortion design meets stringent inspection standards.
