Half-Coated Spheres | Magnetic Half-Shells | Hemispherical Coatings
 We offer unique capability to manufacture spheres with partial coatings. Half-shell or hemispherical coatings can be applied to any sphere (glass, polymer, ceramic), as well as different densities of microspheres. Coatings can be customized for any color and coverage of between 20% to 60% of the sphere.
Small quantity samples of black-and-white spheres are currently offered for sale, for large volumes please contact us for a quote and lead-time.
Microspheres with magnetic half-shells have numerous applications in diagnostics, medical research, microscopy and biotechnology, as well as electronics, due to their ability to orient themselves in response to
electromagnetic field and show a visual response.
 This is achieved by
making spheres both bipolar and bichromal,
with dipole precisely aligned with two differently colored hemispheres. As the spheres align themselves, the viewer will observe
the color of one hemisphere, while the other hemisphere will be hidden
from view, providing an obvious strong visible indication of the
presence of the field.
