PITTSBURGH, Feb. 10, 2021 (GLOBE NEWSWIRE) -- II‐VI Incorporated (Nasdaq: IIVI), a leading provider of imaging optics, today announced the introduction of its diffraction-limited apochromatic ...

Diffractive and refractive lenses are widely used in X-ray analysis and high-resolution X-ray microscopy with many scientific applications in materials science, energy sciences and biology.

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

The article reviews the Stellarvue SV4, a 4-inch apochromatic refractor recognized for its high-quality optics and compact form factor. Central to the SV4's design is a LOMO fully multicoated ...

Previously released for full-frame mirrorless systems, this specialized lens with its industry‑leading 2x magnification and ...

Producing the perfect color images we need and love often requires multiple, heavy lenses so that each color focuses in exactly the same plane. Now engineers have developed a new theory that solves ...

When a single spherical lens is used with a polychromatic light source, different wavelengths do not focus to the same point, creating a colour distortion (colour fringes) within an image. This effect ...

Central sharpness is very good at f/1.2 and f/1.4, excellent from f/2 to f/11, touching on being outstanding at f/5.6. f/16 is very good and it is still good at f/22. Edge sharpness is soft at f/1.2 ...
