Inventor: HOSOE HIDE
IPC: G02B27/02
Filed: 2002-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a plastic-made optical element for a head-up display where a coat film with superior durability can be formed.  <P>SOLUTION: At least one or more other surfaces 14 are formed between an outer circumferential surface 13 and an extension surface 12 and the width Δof the surfaces 14 is set to 0.01 to 10 mm when the surfaces 14 are viewed in parallel to the normal X in the center of an optical surface. Consequently, even when coat droplets are jetted from a sot source, no shadow in formed because of the presence of the surfaces 14, so the coat droplets become easy to fly around to the outer circumferential surface and as the sticking amount increases, the coat film thickness becomes larger to prevent water, etc., from entering, thereby suppressing trouble such as coat peeling.  <P>COPYRIGHT: (C)2003,JPO
