PSI scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens ...

X‐ray optics has emerged as a critical field in modern imaging and fabrication, utilising refractive lenses that enable the precise control and focusing of X‐ray beams. Refractive lenses, particularly ...

Lenses are a part of everyday life—they help us focus words on a page, the light from stars, and the tiniest details of microorganisms. But making a lens for highly energetic light known as gamma rays ...

To cut weight from x-ray space telescopes, Tokyo Metropolitan University is micro-machining x-ray lenses from silicon. To cut weight from x-ray space telescopes, Tokyo Metropolitan University is micro ...

This paper covers a discussion of the Abbe Sine Condition and its implication for Flat Optics, including the effects of stop shift and substrate curvature. Following that, we apply Sweatt’s high index ...
