Abstract

PURPOSE:To make magnification selecting mechanisms simple and to facilitate manufacture and assembling by forming or joining the 1st optical unit and 2nd optical unit which are constituted by superposing >=2 platelike lens arrays by leaving prescribed spacings, to one body. CONSTITUTION:An imaging optical device 10 is constituted by forming respectively corresponding platelike lens arrays in plural optical units of platelike lens array construction to one body. More specifically, the 1st optical unit 11 consists of lens arrays 12, 13, 14, and the 2nd optical unit 15 of separate lens arrays 16, 17, 18. The arrays 12, 16 on object 19, 20 sides, the intermediate arrays 13, 17 and the arrays 14, 18 on image 21, 22 sides are formed of resins to one body respectively as one sheet of platelike lens arrays 23, 24, 25. These may be also formed by making the arrays separately and joining both afterward.
