Key Features
  • Ultra-Bright F2.0 Aperture: Captures pristine images under extremely short exposure times, boosting line scan camera line rates.
  • Flawless Illumination Uniformity (>90%): Offers the highest brightness uniformity in its class, ensuring virtually zero shading artifacts across 4K and 8K line sensors.
  • Compact & Lightweight Structure: Measuring just Φ52 × 63.5mm and weighing 290g, this lens integrates seamlessly into space-constrained multi-camera systems.
  • High-Speed Steel & Metal Film Scan: Scans fast-moving metal sheets, foils, and wires for microscopic surface cracks or structural pitting under short exposures.
  • Logistics & Barcode Sorting: Empowers logistics hubs to run high-speed OCR text and barcode scanning over wide, fast-moving sorting conveyors.
Frequently Asked Questions
  • What makes an F2.0 Large Aperture 4K 8K Line Scan Lens better than an F2.8 lens for high-speed scanning?
    At ultra-high line rates, camera exposure times drop to microseconds. An F2.0 large aperture 4K 8K line scan lens gathers double the light of an F2.8 lens, meaning you can maintain low sensor noise and avoid expensive, overly powerful external strobe lighting.
  • Does this 4K 8K line scan lens maintain sharpness when wide open at F2.0?
    Yes, this F2.0 large aperture line scan lens utilizes specialized high-refractive-index glass elements to maintain excellent MTF contrast and sharpness even at full F2.0 aperture.
  • Can I customize the filter size or mechanics for this line scan lens?
    The lens comes with a standard M43 P=0.75mm filter thread and can be adapted with custom step rings based on specific OEM system requirements.
