Introduction
In machine vision applications, the right lighting is crucial for reliable image recognition. This guide covers the key parameters.
Colour temperature and wavelength
The wavelength of the LED determines which features of the object become visible. White light is suitable for general inspection, while monochromatic light (for example red or blue) can increase contrast on specific materials.
Intensity and uniformity
High and uniform light intensity ensures consistent image quality. VHP offers LED lighting with tight tolerances on intensity distribution.
Pulsed vs. continuous
For fast production lines, pulsed (strobed) lighting is often the better choice: a shorter exposure time freezes motion and extends the lifetime of the LEDs.
