Advanced technologies of microlenses production for robot system camcorders

The processes of formation of microlenses in photosensitive silicate and germanate glasses have been studied. A series of successive operations with samples of photosensitive glass activated by silver and cerium ions: irradiation, photolithography, secondary heat treatment, diffusion and ion exchange lead to the formation of various profiles on the glass surface, including convex or concave lens surfaces. On the basis of this effect, a promising technology for the production of raster microlenses and lenses for various optical devices and video cameras of a robotic system was developed.
