Title: Norbert Kraemer: Innovator in Laser Exposure Technology

Introduction

Norbert Kraemer is a distinguished inventor based in Heidenrod, Germany. He has made significant contributions to the field of printing technology, particularly through his innovative laser exposure apparatuses. With a total of three patents to his name, Kraemer's work has advanced the capabilities of printing forms and exposure techniques.

Latest Patents

Kraemer's latest patents include a laser exposure apparatus designed for printing forms to be imagewise exposed. This apparatus utilizes a laser, beam divider, modulator, beam expander, beam combiner, polygonal mirror, and a scanner lens, along with a path-folding mirror and a reference mask. The laser beam is divided into a writing beam and a reference beam, which are combined using two path-folding mirrors and a beam combiner. The writing beam is directed through an exposure slit onto a printing form, with an additional exposure device positioned either upstream or downstream of the exposure slot. This setup allows for either preexposure or afterexposure in conjunction with the main laser exposure.

Another notable patent is the preexposure device for printing forms, which features a linear LED arrangement for full-area preexposure. This arrangement consists of at least two rows of LED modules that are offset from one another. Each module contains multiple light-emitting diodes, and the entire assembly is housed within a casing that is sealed at the bottom with a light scattering plate.
