<p>PURPOSE:To fix a guide member without using any adhesive. CONSTITUTION:The lens is deformed plastically into a target shape by receiving pressure from both right and left sides at the time of press forming. At this time, the recessed part 3 of the guide member which is arranged around the lens 1 serves for a play in the press forming, so a lens material flows in the recessed part 3. The volume of the lens 1, the quantity of the lens material to be used, and the volume of the recessed part 3 are so adjusted that the lens material flows the recessed part 3 and does not overflow.</p> |
