Do3think Expands Its Dual-Fiber 20 G Platform with a New 8K Line Scan Member

Do3think has just launched the DXL8K4M-H1N-F4 (DXL8K4M for short), a 20GigE dual-fiber 8 k line scan camera built for tight spaces and ultra-high-speed inspection. Its miniaturized mechanics, multi-line high line-rate sensor, pioneering TDI-based time-division stroboscopic lighting, and multi-channel flat-field correction deliver a reliable, high-efficiency imaging solution for demanding high-speed, high-precision applications.

Compact body, massive power

At only 76 × 76 × 65 mm, the DXL8K4M highly integrated industrial design offers the smallest footprint in its class, giving vision-system builders a flexible, streamlined mounting solution.

Ultra-high line rate – a new benchmark in speed

Multi-line modes:

• 58 kHz in 4-TDI
• 90 kHz in 2-TDI
• Up to 240 kHz in single-line mode
  These rates dramatically boost acquisition speed to meet the throughput of the fastest production lines.

Taming low light and mixed lighting

With 7 µm large pixels, the sensor captures nearly twice the light of typical 5 µm pixels. Coupled with the industry-first “TDI time-division stroboscopic + multi-channel flat-field correction” technology, the camera reduces the number of required stations while further boosting sensitivity, responsivity, and signal-to-noise ratio. Users can switch on the fly between 2-line and 4-line TDI modes to deliver bright, sharp, detail-rich images in high-speed, low-reflectivity, or low-light environments.

FPGA frame grabber – blazing-fast, rock-solid data flow

The matching high-performance FPGA frame-grabber eliminates data-transfer bottlenecks from the ground up, ensuring loss-free, ultra-fast transmission. By off-loading intensive pre-processing tasks from the host CPU, it slashes system load and keeps the main control system responsive even with massive data volumes.

Rich ISP toolkit for premium image quality

On-board FPN correction, multi-channel flat-field correction, contrast enhancement and other professional ISP functions optimize image quality in real time.

Fiber optics – reach without compromise

Dual-fiber interfaces provide strong immunity to EMI and allow cable runs up to 300 m, eliminating the attenuation and interference issues of long copper links.

Low power, high reliability

Total power consumption < 10 W minimizes thermal noise and simplifies thermal management. Continuous 24/7 operation is assured without bulky heat sinks.

Proven across industries

The DXL8K4M is already deployed in lithium-battery coating, film/web inspection, PCB/ AOI, semiconductor, packaging & printing, and other surface-defect inspection applications.
