Abstract
When an optical device is produced by bonding on a transparent base member an optical element formed as a hologram, the optical element and the transparent base member are both formed of an acrylic material. In particular when, as an optical device, an eyepiece optical system is produced by holding an optical element between two transparent base members, the optical element, the transparent base members, and the adhesive with which the transparent base members are joined together are all formed of an acrylic material. In this way, by building an eyepiece optical system with a similar kind of material, namely an acrylic material, it is possible to obtain increased adhesion among the materials of the individual components of the eyepiece optical system without performing special processing. Moreover, the transparent base members formed of an acrylic material more securely absorb shock and external pressure than those formed of glass.
