Concept and application of spectroscope in coaxial light source for machine vision
Coaxial light source: The surface light source adopts a beam splitter design. Suitable for surface areas with different roughness, strong reflection or unevenness, detecting carved patterns, cracks, scratches, separation of low and high reflection areas, eliminating shadows, etc. It should be noted that the coaxial light source has a certain amount of light loss due to spectral design, and brightness needs to be considered, and it is not suitable for large-area illumination. Applications: contour and positioning detection of glass and plastic films, IC character and positioning detection, chip surface impurity and scratch detection, etc.
A spectroscope is a lens that allows light to partially pass through and partially reflect to achieve the splitting effect. Our company produces spectroscopes with wavelengths ranging from 250nm to 1700nm (ultraviolet, visible light, near-infrared, optical communication bands, etc.), which have no ghosting, small PDL values, clear imaging, small splitting ratio errors, and can be purchased in large quantities.
