Device and Method for Generating Monochromatic Radiation from a Radiation Source with Line Spectrum

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a device and method for generating monochromatic (single-wavelength) radiation from a radiation source with a line spectrum, such as gas discharge lamps. It uses at least one off-axis reflection zone plate to selectively separate a specific spectral line from the broader line spectrum. A diaphragm is then used to isolate the desired line, optimizing both efficiency and spectral purity. The system can be cost-effectively integrated and aligned, and is particularly suited for applications requiring high-purity monochromatic light.

Patent Abstract

The invention relates to a device and method for generating monochromatic radiation of a radiation source with line spectrum. Said device comprises at least one radiation source (1) which produces a line spectrum, and an off-axis reflection zone plate (3). According to the invention, the off-axis reflection zone plate (3) is designed to separate a predetermined spectral line of the radiation source line spectrum. A diaphragm (4) is located in the optical path downstream of the off-axis reflection zone plate (3) at the location of a local image of the predetermined spectral line.
