VCSEL in Machine Vision: Real-World Applications

Understanding VCSEL Technolog

What is a VCSEL?

VCSELs (vertical emission semiconductor lasers) are different from edge-emitting lasers in that VCSELs are small, efficient, long-lived, and can be used in a variety of applications.

Why are VCSELs important for machine vision?

VCSELs produce focused coherent beams that provide high quality light for imaging systems to capture and analyse images.

How do VCSELs work in machine vision?

VCSELs are often mounted with cameras or sensors and controlled by the same electronics. The intensity and direction of light is precisely controlled to obtain accurate imaging results.

Advantages of using VCSELs in machine vision

Precision Illumination

Used to illuminate small areas with high precision for accurate measurements, such as when inspecting microelectronic components or small objects.

Long Lifetime

The longer lifetime of VCSELs compared to conventional edge-emitting lasers means that they require less additional cost, making them an attractive option for industrial and commercial applications.

Small size and low power consumption

The small size and high efficiency of VCSELs allow them to be easily installed in a variety of systems without adding bulk or weight, making them ideal for portable and mobile applications.

Practical applications of VCSELs in machine vision

Industrial Automation

They are very common and are often used to inspect parts, measure distances and perform other tasks. In use, these systems allow for a higher level of image quality.
