Advantages of the 14X High-Precision ZOOM LENS

1. A wider range of magnification：14X lenses typically cover 0.55X to 7.6X magnification.

(1) Low-magnification macro scanning: Rapidly locates defect areas across entire wafers or large circuit boards;

(2) High-magnification micro inspection: Clearly displays nanoscale circuit lines and minute defects (e.g., width and spacing of 7nm process transistor gates).

2. Shorter working distance: The 14X lens has a working distance of approximately 77.8mm, compared to 87mm for traditional lenses.

This reduced distance enables : Inspection of high-density electronic components within confined spaces (e.g., BGA-packaged chips with 0.3mm pitch on iPhone motherboards);Minimized light propagation loss, enhancing imaging contrast and brightness for more precise defect identification.

3. Optimized depth-of-field control

Conventional lenses exhibit shallow depth-of-field at high magnifications, making it difficult to simultaneously capture clear images of multi-layer structures (e.g., plated-through holes on multilayer PCBs). The 14X lens maintains superior depth-of-field at high magnifications through optimized optical design, fully revealing details across all layers and reducing the risk of missed defects.

4. Enhanced Inspection Efficiency

The wide magnification range minimizes lens changes and eliminates frequent equipment parameter adjustments for inspections with varying precision requirements, making it ideal for high-efficiency inspection on large-scale production lines.

Suitable Scenarios for 0.7X-4.5X Lenses

• Large-size PCB Inspection: Traditional lenses with long working distances (87mm) and deep depth of field advantages are suitable for inspecting large-area PCBs with minimal height variations, avoiding collision risks caused by excessive proximity between the lens and the object under test.

• Non-contact inspection requirements: In scenarios demanding safe distances (e.g., fragile or sensitive materials), the long working distance of traditional lenses minimizes damage from electrostatic adhesion or mechanical impact on test subjects.

• Cost-sensitive applications: For scenarios with lower precision requirements or budget constraints, traditional lenses may offer better cost-effectiveness.

The high-precision 14x ZOOM LENS offers advantages over the 0.7x-4.5x lens in specific scenarios, but it is not universally superior in all situations. A comprehensive evaluation based on specific requirements is necessary.
