ASIO Vision markets in Israel a unique and innovative lighting solution based on a laser light source, offering a replacement for conventional LED lighting.
The lighting system is based on a laser that launches an optical signal into a nano-active optical fiber. The optical signal interacts with the fiber’s unique internal structure, generating a large number of point-like light sources distributed along the fiber. This process enables the creation of powerful, uniform, and highly precise illumination, with advanced control over light direction and emission angle.
Principle of Operation
A laser launches an optical signal into a multi-material, engineered optical fiber that integrates nano-active structures. The optical signal interacts with two different types of structures embedded within the fiber:
- Glass nano-antennas
- Active pigments
The nano-antennas are three-dimensional glass nanostructures integrated inside the optical fiber. Their role is to provide controlled directionality of the optical field emitted from the side of the fiber.
The three-dimensional shape, strength, and location of these nano-antennas make it possible to precisely design the side-lighting emission angle — ranging from a few degrees up to several tens of degrees – at any point along the engineered optical fiber.
This technology, known as LuxiBright, was developed by the Swiss company L.E.S.S and is marketed in Israel by ASIO Vision.
Example 1: Coating Quality Inspection in Holes – Hole Inspection
In applications involving inspection of coatings inside tiny holes (such as electronic connectors), the use of standard coaxial illumination often produces only minimal visual differences between acceptable areas and defective ones. This typically requires the use of complex and costly Deep Learning solutions to detect the variance.
By contrast, using the LuxiRing illumination makes areas with missing coating clearly visible and easy to identify, even with entry-level cameras or sensors. This enables significant system simplification and reduces the overall solution cost for the customer.
Example 2: Photonic Bonding Inspection – Photonic Bonding
Inspection of conductors and delicate wire bonding requires exceptionally high sharpness to verify connection integrity. Compared to traditional LED lighting, L.E.S.S technology enables much sharper and more precise edge detection.
Thanks to the high directionality and uniformity of the illumination, transitions between different image regions appear clearer and less noisy. As shown in the image, the bonding wires are clearly visible, allowing the machine vision system to define edges using fewer pixels, optimize effective resolution, and improve measurement accuracy.
