ABSTRACT:
A projecting device is disclosed which has plural element lens systems arranged in at least two rows in a staggered fashion in two grooved blocks, with one row displaced relative to the adjacent row by a distance equal to half the pitch of the adjacent row. Each lens system is composed of at least one bar lens for imaging a part of the object as a part of the corresponding image. An opaque elastomer material fills the space between the rows for preventing light from entering into the space while allowing the positional relation between the rows to be fine-adjusted.
