Introduction to Zoom Lenses

Zoom lenses have become a key component in machine vision due to their dynamic focal length adjustment capabilities. Their core feature is the ability to continuously adjust the focal length and magnification by moving the internal lens group, covering multi-scale inspection requirements from macro layout to micro details without changing lenses.

Advantages of Zoom Lenses

1. Improved flexibility and efficiency: In electronic component inspection, the 6.5X zoom lens can quickly switch to 12.5X high magnification to simultaneously complete the overall layout inspection of the circuit board and chip pin defect analysis, improving inspection efficiency by more than 40%.

2. High-precision imaging: POMEAS 4K zoom lenses use a large target surface design with a resolution of 3840×2160 pixels, which is 1.45 times wider than traditional lenses, allowing for clear capture of 0.01mm scratches and gold wire deviations on the chip surface.

3. Automation compatibility: The electric zoom lens supports PLC and vision software linkage, achieving 0.1-second magnification switching in automotive parts inspection. Combined with a gigabit industrial camera, it meets the high-speed production line cycle requirements.

Typical Application Scenarios

1. Precision manufacturing: Inspects the surface roughness of miniature gears and uses the zoom function to perform step-by-step analysis from the overall morphology to the local tooth pattern.

2. Semiconductor industry: In wafer inspection, the 4K zoom lens combined with a coaxial light source can identify 0.5μm-level circuit defects, improving the yield rate by 15%.

3. Medical equipment: Surgical microscopes use zoom lenses to support real-time magnification adjustment from macro tissue positioning to capillary suturing, with surgical accuracy reaching 0.02 mm.

Through dual optimization of optical design and mechanical structure, the POMEAS zoom lens series provides a “one lens for multiple uses” solution for machine vision systems, helping the manufacturing industry upgrade towards intelligence and refinement.
