TELESCOPIC KALEIDOSCOPE

摘要

A telescopic kaleidoscope having a converging lens positioned between the objective lens and the front ends of the mirrors. The converging lens focuses the objective lens centrally on the plane of the rear ends of the mirrors to provide substantially equal illumination of the kaleidoscope image array. The array can be projected onto a screen by a projection lens and the kaleidoscope can be used as an attachment for a camera or a projector.
