Science Now – making a lens for highly energetic light known as gamma rays had been thought impossible. Now, physicists have created such a lens, and they believe it will open up a new field of ...

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 ...

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 ...

Ray Optics often overwhelms Class 12 students due to formulas and sign conventions. An expert board examiner explains why rote learning fails and how visual thinking, ray diagrams, and conceptual ...
