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 ...

“Diffractive and refractive optical elements have become an integral part of most high-resolution X-ray microscopes. However, they suffer from inherent chromatic aberration. This has to date ...

The achromatic doublet lens is used to minimize or eliminate chromatic aberration. Its achromatic design also helps to minimize spherical aberration. Compared with a single lens, an achromatic doublet ...

Although Antoni van Leeuwenhoek has rightly earned his reputation as the founder of microbiology and the maker of fine simple microscopes, it was a contemporaneous and largely unknown mid-17th-century ...

A microscope objective lens produces a real, magnified image of an object placed within the field of view. Before it is observed the image is then magnified again by the ocular lens, also known as the ...
