[1] Lighting equipment
Lighting for the workpieces is an important factor in image processing. The lighting conditions affect the
measurement results. Select the proper lighting equipment.
- Make sure there is uniform illumination of the whole measurement field where object images will be
taken.
- Use flicker-free lighting equipment, such as a high frequency fluorescent lamps or halogen lamps.
- Consult us about the right lighting equipment for your application.
(1) Backlighting
Light should uniformly illuminate the field behind an object, so that the IV-C35M measure the object
with it's shadow. Since the shadow picture will be converted to binary values, reliable measurements
can be executed.
Example:
(2) Reflective lighting
A light shone on the front of an object with angle will be reflected, and the IV-C35M will pick up the
reflected light. If too much light is reflected, such as from a metallic surface or similar materials, a
proper image may not be obtained.
