Abstract
Official abstract text for this publication.
A lens array is provided in which the edges of concave-shaped lens faces can be formed with high accuracy and the accuracy of position measurement of the lens faces can be improved. Outer peripheral edge portions 7 a of a plurality of lens faces 7 are formed in positions further towards face apex portion sides than a predetermined surface 2 with cylindrical stepped surfaces 12 for each lens face 7 therebetween, one end of the stepped surfaces 12 being the outer peripheral edge portions 7 a and another end being a plurality of opening portions 2 a formed on the predetermined surface 2 such as to respectively face the outer peripheral edge portions 7 a.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lens array formed using a mold, the lens array comprising: a plurality of lens faces formed in an array along a predetermined array direction on a predetermined surface of a lens array main body, in which the plurality of lens faces are concave-shaped lens faces that recess inward from the predetermined surface such that face apex portions of the lens faces are farther away from the predetermined surface than are outer peripheral edge portions of the…
