OPTICAL RECORDING LENS ASSEMBLY AND ITS MANUFACTURING METHOD

PROBLEM TO BE SOLVED: To provide an optical recording lens assembly and a manufacturing method for the optical recording lens assembly by which the increase of a transmission wave front aberration is controlled, a non-hardened adhesive does not remain and a lens and an spacer ring are fixed with high precision. SOLUTION: In the optical recording lens assembly wherein the lens 4 and the interval ring 5 are housed in a lens frame 1 in the cylindrical part of which a plurality of through-holes 3 are provided and the lens 4 and the spacer ring 5 are fixed by a photosetting adhesive 50 poured from the through-holes 3, a plurality of light guide ring members 9 is provided in the gap 6 between the lens 4 and the spacer ring 5 and the inner surface of the lens frame 1, guided light is propagated and also light enough for hardening the photosetting adhesive 50 is radiated from the surface by the light guide members 9. Thus, the photosetting adhesive 50 is substantially and completely hardened.
