18-Channel DFB Coaxial/Butterfly Light Source Wavelength Can Be
Customized
Butterfly light source: Not a common light source type term, may be
related to the butterfly laser (DFB laser), but the latter is more
used in areas such as fiber optic communications and fiber sensing,
rather than machine vision. In the field of machine vision, coaxial
light sources, strip light sources, ring light sources and so on
are usually discussed.
Coaxial light source: that is, the illumination direction is
parallel to the lens optical axis of the machine vision dedicated
LED light source. It provides more uniform illumination than
traditional light sources while avoiding the reflection of objects,
thus improving the accuracy and reproducibility of machine vision.
An 18-channel coaxial light source may refer to a coaxial light
source system with 18 independent channels, each of which can be
controlled independently to provide different lighting conditions
or effects.

Applications: This multi-channel light source system may be used in
machine vision applications that require a high degree of
flexibility and precise control, such as the detection of complex
surfaces, multi-feature recognition, etc.
Advantages:
Flexibility: The multi-channel design allows users to adjust the
lighting parameters of each channel as needed to achieve the best
imaging results.
Accuracy: Independent channel control can provide more precise
lighting control, helping to improve the accuracy and reliability
of machine vision systems.
Scalability: Multi-channel systems are easy to scale and can add
more channels or features as needed.
