Microspheres
Microspheres
Microspheres offer a practical solution for channeling light into or out of optical fibers and transmitting images within confined spaces. These precision-engineered spherical particles provide near-perfect coupling due to the exceptionally close proximity of their focal point to the sphere’s surface, enabling seamless connection with optical fibers or other microspheres. Avantier manufactures custom microspheres tailored to meet the demanding requirements of fiber optic systems, biomedical imaging, and advanced photonics applications.
