Abstract

An integrator unit for integrating an incoming light beam for a uniform distribution of illumination comprises an inner cylinder fixedly equipped with a rod integrator, an outer cylinder in which the inner cylinder is coaxially received for axial movement and axial adjustment members which comprises a circumferential groove spatially squared to a center axis of the inner cylinder and a radial access bore formed in the outer cylinder. A round shaped position adjustment tool has an end pin on a round end face thereof in a position off center from an axis of rotation of the position adjusting tool. The position adjusting tool is inserted in the radial access bore to put the end pin in the circumferential groove and turned in the radial access bore so as thereby to move the inner cylinder axially back and forth.
