III. Functional Features

(I) High-Precision Wide-Width Imaging for Capturing Micro-Defects

• High-Resolution Linear Acquisition: The 6400-pixel linear sensor can cover a wide inspection area (e.g., when matched with a 16mm lens, the inspection width is approximately 22mm; when matched with a 100mm lens, the inspection width is approximately 140mm). The single-pixel precision reaches 7μm (physical pixel size), and can be further improved to 0.5μm through sub-pixel interpolation, enabling the capture of micrometer-level defects. For example, in film inspection, it can detect pinholes with a diameter of 5μm (about the size of 1 pixel) or scratches with a width of 10μm (about the width of 2 pixels), preventing unqualified products from flowing downstream.

• 
  

• High Sensitivity and Dynamic Range: The high sensitivity of 18V/(lux・s) enables clear imaging under low light intensity (e.g., 500lux), and the 60dB dynamic range can simultaneously present details of bright and dark areas on the object surface. For example, in metal sheet inspection, where the sheet surface has reflective areas (bright areas) and oxidized dark spots (dark areas), the camera can clearly capture micro-scratches (10μm) in reflective areas and corrosion points (20μm) in dark spot areas without overexposure or underexposure.

• Real-Time Image Preprocessing: The built-in preprocessing chip supports bad pixel correction (automatic shielding of invalid pixels), shading compensation (elimination of image brightness deviation caused by uneven light sources), and gain equalization (unification of sensitivity differences among pixels). For example, in paper inspection, the brightness of the edge area of the light source is low, resulting in dark image edges. The shading compensation function can automatically increase the brightness of the edge area, making the brightness of the entire image uniform and avoiding missed detection of defects in the edge area.

(II) High-Frame-Rate Transmission for Matching High-Speed Production Lines

• High Line-Rate Acquisition: The maximum line rate of 12,000 lines/sec can match high-speed production lines. For example, in printed product inspection, if the printing machine speed is 100m/min (approximately 1.67m/s) and the inspection width is 50mm (each line of image covers a width of 50mm), the required line rate = 1.67m/s ÷ 0.05m/line = 33.4 lines/sec. The camera's line rate of 12,000 lines/sec is much higher than the requirement, leaving sufficient margin to cope with production line speed increases (e.g., up to 150m/min).

• 
  

• High-Speed Transmission via Dual Interfaces: The Camera Link interface (2.048Gbps) and Gigabit Ethernet interface (1Gbps) support high-speed data transmission. At full resolution (6400 pixels), the Gigabit Ethernet interface can meet the real-time transmission requirement of 12,000 lines/sec (data volume per line = 6400 pixels × 12 bits = 9600 bytes; the rate corresponding to 12,000 lines/sec = 9600×12,000 = 115,200,000 bytes/sec ≈ 110Mbps, which is lower than the 1Gbps bandwidth), with no data loss.

• Trigger Synchronization Control: Supports hardware triggering (e.g., encoder triggering) and software triggering, with a trigger delay ≤1μs, enabling synchronization with production line movement. For example, in metal coil inspection, the encoder generates pulse signals when the coil moves, and the camera receives the pulses to trigger acquisition (1 line acquired per pulse), ensuring accurate alignment between the image and the coil position and avoiding image stretching or compression caused by fluctuations in coil speed.

(III) Industrial-Grade Reliability for Adapting to Harsh Working Conditions

• Hardware Protection and Anti-Interference:

• The metal housing and internal shielding design can resist electromagnetic interference. Near frequency converters (output power 50kW) or servo motors (10kW) (electromagnetic radiation ≥8V/m), the images captured by the camera have no noise or stripe interference, and the defect detection accuracy remains unchanged.

• The power circuit adopts a "two-stage isolation (isolation voltage ≥2500Vrms)" design to suppress the impact of grid voltage fluctuations (e.g., 12VDC fluctuation ±10%) on the camera, ensuring no changes in image brightness and frame rate.

• 
  

• Wide-Temperature Adaptability and Durability: The operating temperature covers 0℃~+50℃. In high-temperature inspection workshops in summer (45℃) or unheated workshops in winter (5℃), the camera's imaging quality and transmission rate do not degrade. The metal housing supports continuous operation for more than 10,000 hours without component overheating or performance degradation.

• Fault Self-Diagnosis: Supports monitoring of the camera's working status (e.g., temperature, power voltage, interface connection) via software (such as DALSA Sapera LT). When "low power voltage (<10.8V)" or "Camera Link interface disconnection" is detected, it outputs a fault signal to the upper system and saves the current configuration parameters to avoid parameter loss after restart. For example, if the production line suddenly loses power and then resumes, the camera automatically loads the previous parameters such as exposure time and gain, requiring no reconfiguration and enabling quick resumption of inspection.

(IV) Flexible Configuration and System Integration

• Multi-Lens and Light Source Compatibility: Supports C-mount/CS-mount lenses; lenses with different focal lengths can be selected according to the inspection width (e.g., 8mm lens for narrow-width inspection, 100mm lens for wide-width inspection). It supports matching with various light sources (such as LED line light sources and laser line light sources), and controls the synchronous activation of the light source via the flash synchronization interface to improve image contrast. For example, when inspecting transparent films, matching with a 450nm blue LED line light source makes film defects (such as bubbles) show high contrast under blue light irradiation, allowing the camera to capture them accurately.

• 
  

• Compatibility with Multiple Software Platforms: Supports mainstream industrial vision software platforms, including DALSA Sapera LT, Halcon, VisionPro, etc., and can directly call the camera driver for parameter configuration and image acquisition. For example, in the inspection of electronic component pins, engineers use Halcon software to call the camera, configure an exposure time of 10μs and a gain of 0dB, capture pin images in real time, and perform dimensional measurement (such as pin width and spacing) with a measurement precision of ±1μm.

• Batch Configuration and Upgrade: Supports batch configuration of parameters for multiple cameras via the Ethernet interface (e.g., configuring the exposure time and trigger mode for 10 cameras simultaneously) and supports online firmware upgrade. For example, a food packaging inspection line is equipped with 5 cameras; batch setting of "exposure time 20μs, line rate 5000 lines/sec" via software reduces the configuration time from 10 minutes to 1 minute. During firmware upgrade, there is no need to disassemble the camera; the new firmware (approximately 512KB) is uploaded via the network, and the upgrade time is ≤30s.
