Refractive sphere

WebSpherical ball lenses have been used as collimators in fibre optic connectors. Sapphire spheres with a high refractive power are industrially produced in a wide range of diameters (Sandoz SA, Cugy, Switzerland; Rubis Precis, Charquemont, France). Light emitted from a fibre can be focused with this lens type onto the sample site (Figure 12A).Rol found a … WebA sphere will transmit the same refraction pattern regardless of its orientation. In a measuring system where the spherical particle is constantly changing orientation with respect to the incident light, the pattern is always identical and can give rise to well-defined, reinforced extraneous information that can distort or interfere with the ...
