This invention belongs to the field of optical component mounting technology, specifically a real-time coaxial
optical coupling loss detection and alignment
system for prisms and lens arrays. It includes an automatic loading and unloading module for automatically loading the substrate, prisms, and lens arrays, and automatically sorting and unloading qualified and unqualified products. By adopting a technical solution that uses the real-time coaxial
optical coupling loss detection value as the sole criterion for final alignment of the
lens array, combined with a graded alignment strategy of visual coarse alignment and coaxial optical fine alignment, it solves the common industry pain point of existing pure visual alignment and passive alignment technologies that separate physical dimensional accuracy from optical performance. This results in the inability to compensate for manufacturing errors such as uneven
refractive index and
surface flatness deviations within optical components, leading to substandard optical performance despite meeting physical accuracy standards and low yield rates in
mass production. By using dimensional and angular tolerances only as auxiliary constraints, it directly locks the global minimum
coupling loss point, improving the consistency and stability of the product's optical performance.
