Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

Sieve analysis continues to be the traditional and most widely used technique for particle size determination. A sieve stack contains a number of sieves with increasing aperture size stacked upon each ...

Fundamental diffraction physics says that a larger aperture improves both resolution and penetration. However, aperture size has historically been limited by system complexity and unknown benefit in ...

Place the laser on top of the lab jacks, making sure the laser is pointed away from people. Place the slide mount on the optical rail and insert the sample slide to the slide mount. Plug in the laser ...

Factors that can affect lens performance, and how to overcome them. Lens technology has come a long way over the past two decades and many photographers are prepared to invest in high-performance ...

A new imaging technology developed at the University of Connecticut promises to rewrite the rules of optical imaging, enabling ultra-high resolution views without relying on bulky lenses or ...

Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...

This is the widest aperture that can be selected on the camera and is an indication of the speed of the lens. On zoom lenses two figures are often given. One is for the lens at the wide-angle setting ...
