Why Specialized Macro Lenses Are Essential for Micro-Component Inspection

Ordinary general-purpose lenses are not designed for close-range micro observation. Industrial-grade macro lenses are uniquely optimized for high-precision inspection work.

• Ultra-high magnification to capture micron-level tiny defects and surface scratches
• Strict low distortion design to ensure accurate dimensional measurement data
• High-definition optical structure to adapt to 5MP, 8MP and 12MP industrial cameras
• Stable fixed working distance, suitable for assembly line automatic inspection
• Multi-layer anti-reflection and IR correction coating for stable imaging in complex light
• Compact and standardized mounting structure for easy integration into inspection machines

Key Technical Parameters of Industrial Inspection Macro Lenses

Master these core specs to avoid mismatched models and unstable imaging effects:

• Image Distortion: Critical for dimensional measurement and defect detection accuracy
• Field of View (FOV): Defines the effective shooting range for tiny electronic parts
• Working Distance (WD): Fixed installation distance between lens and inspected objects
• Sensor Size Compatibility: Supports 1/3”, 1/2”, 1/1.8” mainstream industrial sensors
• Aperture Specification: Adjusts light intake and depth of field for clear close-range shooting
• Mount Interface: Determines compatibility with industrial cameras and inspection devices

Step-by-Step Macro Lens Selection Guide for Micro-Component Inspection

1: Confirm inspection object and defect types

• Record the overall size of micro-components
• Clarify detection targets: scratches, pin gaps, solder defects or size tolerance

2: Sort out your camera specifications

• Confirm camera resolution, pixel density and sensor size
• Match lens image circle to avoid dark corners and blurred imaging

3: Confirm required magnification and FOV

• Wide FOV + low magnification for batch large-area scanning
• High magnification for local micro defect close-up inspection

4: Select the correct mount type

• M12 macro lens: compact, cost-effective for mini inspection equipment
• C/CS macro lens: industrial grade, stable performance for long-term assembly line use

5: Confirm special functional requirements

• IR correction for low-light or night vision inspection
• High temperature and vibration resistance for harsh factory environments
• Non-standard focal length or working distance for customized equipment

FAQs

Q1: Macro lens vs telecentric lens, which one for micro inspection?

• Macro lens: Ideal for surface detail observation, scratch and appearance defect detection
• Telecentric lens: Better for ultra-precise size measurement with zero perspective error

As a professional macro lens manufacturer, TOWIN provides both series for diversified demands.

Q2: Can your macro lenses fit my existing industrial camera?

Yes. Our lenses cover mainstream sensor sizes and universal M12, C, CS mounts. Send your camera parameters, and we offer free professional matching suggestions.

Q3: Why is low distortion essential for micro-component inspection?

High distortion causes edge blur and size calculation deviation, leading to wrong quality judgment. Low-distortion macro lenses are a must for industrial precision inspection.

Q4: Do you support sample testing before bulk orders?

Absolutely. We provide sample services to help you test imaging performance and compatibility, reducing procurement risks.

Q5: What are your production and delivery cycles?
