Telecentric
At the exit of a telecentric illumination, the light is collimated. The collimated light is a parrallel structure of light rays from a point source. The illuminated area and light intensity remain the same whatever the distance.

What is telecentric lighting in machine vision?
Telecentric lighting is a specialized illumination technique designed for high-precision imaging and dimensional measurement applications.
Unlike conventional lighting, telecentric illumination generates highly collimated light rays that travel in parallel. This creates sharp and accurate object silhouettes, minimizing optical distortions and improving measurement accuracy.
Telecentric lighting is commonly used in machine vision systems where repeatable and reliable dimensional measurements are critical.
What are the main advantages of telecentric lighting?
Telecentric lighting offers several advantages compared to standard backlighting solutions:
- extremely sharp edge definition
- reduced measurement errors
- improved dimensional accuracy
- superior repeatability
- minimized influence of object position variations
What applications are telecentric lighting systems used for?
Telecentric lighting is widely used in applications that require accurate dimensional measurements and high inspection repeatability.
Typical applications include:
- dimensional measurement and metrology
- diameter and thickness inspection
- edge detection
- measurement of holes and cut-outs
- precision positioning and alignment
- quality control of manufactured components
Are telecentric lighting systems compatible with industrial cameras?
Yes. Telecentric lighting systems can be integrated with most industrial machine vision cameras.
They are commonly used alongside:
- area scan cameras
- line scan cameras
- telecentric lenses
- metrology-grade vision systems
