Understanding Scanner Speed in Laser Systems: kpps Explained

In laser scanning systems, scanner speed is a critical performance parameter measured in kpps (kilo points per second), which indicates how many thousands of points the laser can position per second. This specification directly impacts the quality, precision, and application range of laser systems.



What is kpps?

kpps (kilo points per second) represents the scanning speed of galvanometer mirrors. Higher kpps values mean the laser can process more points in the same amount of time, resulting in smoother curves, finer details, and faster operation.



Common Scanner Speed Tiers and Their Applications

1. 20 kpps Systems

  • Performance: Entry-level speed, suitable for basic applications.

  • Line Quality: Slight cornering visible in curves; best for simple graphics.

  • Best For:

    • Wood engraving

    • Simple text marking

    • Low-detail graphics

  • Limitation: Not ideal for high-speed or high-precision tasks.


2. 30 kpps Systems

  • Performance: Mid-range speed, offering a balance of speed and quality.

  • Line Quality: Smoother curves with minimal cornering; improved detail resolution.

  • Best For:

    • General-purpose engraving

    • Medium-complexity graphics

    • Industrial marking

  • Advantage: Versatile for most commercial applications.


3. DT40 50-60 kpps Systems (High Performance)

  • Performance: High-speed scanning with exceptional precision.

  • Line Quality: Virtually no visible cornering; excellent for fine details and complex designs.

  • Best For:

    • High-speed precision marking

    • Complex graphics and fine details

    • 3D laser scanning

    • Dynamic laser shows

  • Benefit: Superior speed and accuracy for demanding applications.

    

Why Does Scanner Speed Matter?

Smoothness: Higher kpps values produce smoother curves and reduce visible corners.

Speed: Faster processing increases throughput in production environments.

Precision: Essential for detailed graphics and high-accuracy applications.

Versatility: Determines the range of applications the laser system can handle.



Choosing the Right Scanner Speed

  • For hobbyists or simple tasks: 20 kpps systems are cost-effective.

  • For most commercial applications: 30 kpps offers a great balance of performance and price.

  • For high-end industrial use: DT40-level scanners (50+ kpps) provide the speed and precision needed for demanding tasks.

    

Scanner speed (kpps) is a key factor in selecting a laser system. Understanding the differences between 20 kpps, 30 kpps, and high-performance options like DT40 scanners ensures you choose the right technology for your specific needs, balancing cost, speed, and quality.
