Patent ID: 7223952

Claim:
An optical sensing head for sensing laser radiation reflected by an optical data memory and for reading out the optical data memory, the optical sensing head comprising: a substrate having a main surface extending along a first main plane; an edge-emitting laser component for emitting laser radiation along an irradiation axis oriented essentially parallel to said first main plane, said laser component configured on said main surface of said substrate; a deflection device configured on said main surface of said substrate, said deflection device for providing deflected laser radiation in a direction essentially perpendicular to said main surface by deflecting the laser radiation emitted by said laser component; at least one signal detector for sensing the laser radiation reflected by the optical data memory; an optical element for guiding the deflected laser radiation to the optical data memory and for guiding the laser radiation reflected by the optical data memory to said signal detector; and a supporting element connecting said optical element to said substrate; at least one of said supporting element and said deflection device being produced from glass and being nondetachably connected to said substrate by an anodic bond.
