Technical Specifications

How to Choose a Model

For 4K@60 fps high-definition dynamic quality-inspection workflows

With native 3840 × 2160 4K resolution and 60 fps real-time frame rate, it captures blur-free imagery of moving workpieces on production lines. Tiny defects such as PCB traces, chip pins and micro-scratches are clearly rendered for high-standard visual-inspection requirements.

For universal observation of large and miniature parts with precision zoom positioning

0.7 ×-5.0 × continuous optical zoom with position-lock function; electronic magnification ranges 21-150 × (expandable to 210 ×). It supports full-frame overview of complete workpieces as well as close-up micro-detail viewing, without image shift after zoom adjustment.

For multi-workstation and remote-network monitoring scenarios

Triple output ports: HDMI, USB3.0 and LAN. HDMI connects directly to monitors for on-site viewing without a host PC; USB links to computers for advanced analytical work; LAN enables local-network remote monitoring to support factory multi-station management.

For high-precision dimensional-measurement with multi-unit conversion

Dual-measurement modes: direct on-monitor measurement and PC-software-based measurement. Measurement accuracy reaches 0.002-0.005 mm *(Smaller measurement tolerance can be achieved under higher magnification. Results subject to calibration, magnification and sample conditions)*. Four switchable measurement units (mm, μm, mil, inch) satisfy tolerance-inspection requirements for hardware, molds and electronic components.

For inspection-data archiving and quality traceability

Three flexible storage pathways: USB flash-drive, PC-USB storage and LAN-software storage. Inspection photos and videos can be saved in batches for generating formal test reports and enabling full-process product-quality traceability.

Differences from Conventional Digital Microscopes

Imaging resolution: Delivers true-4K imaging with abundant fine details; supports seamless cropping and magnification without image blurring, producing large-format displays free of grainy artifacts.
Conventional digital microscopes: Most offer only 1080p / 2K resolution; visible mosaic artifacts and jagged edges often appear under magnification.

Measurement capability: Pixel-level measurement performance with 0.002-0.005 mm precision; supports length, angle and radius measurement plus data export to satisfy industrial micron-level sampling workflows.
Conventional digital microscopes: Limited to basic distance measurement with low accuracy; generally unable to generate formal inspection reports, suited only for preliminary visual checks.

Image Retention: Supports 4K photo capture and video recording. Captured assets can be directly referenced within quality-inspection reports and used as defect-sample retention evidence.

What Problems Can 4K-Resolution Solve?

● Large-format field-of-view balances full-workpiece overview and fine-detail resolution. At low magnification, frequent objective-lens switching is unnecessary; defects such as scratches, edge chipping and micro-cracks can be captured efficiently.
● Cropped local magnification without image blurring; defect details remain clearly visible to accelerate fault identification.
● High-resolution output is ideal for archiving and report-generation; captured field-images can serve directly as quality-inspection records and defect-evidence documentation.
● Large-monitor output free of pixelation and jagged contours; fully compatible with 27-inch and larger displays for crisp edge rendering.
● Higher pixel density reduces pixel-level measurement error, well-suited for measuring tiny gaps and pin-feature dimensions.
