A single device for components of all shapes, with automatic rotation making it possible to measure every side of a part in one complete cycle. Metrios Re-Light offers a wide working field, fast ...

Two parallel optical surfaces often exhibit colorful fringes along the lines of equal thickness because of the interference of light. This simple phenomenon allows one to observe subwavelength ...

Optical Surfaces Ltd (www.optisurf.com) offers a range of standard and custom Precision Flats up to 600mm in diameter manufactured of high-stability materials such as glass, Zerodur and silica.

Optical methods for topography, also known as optical profilometry technique, use light to determine morphology, roughness and other details of a surface. Achieved a number of different ways, optical ...

Measurements of biomechanical properties inside living cells require minimally invasive methods. Optical tweezers are particularly attractive as a tool. It uses the momentum of light to trap and ...

Irregularities on a surface determine how rough it is. Surface roughness can be evaluated by visual appearances and tactile sensation and can be measured using a numerical scale. A surface condition ...

WASHINGTON -- For the first time, researchers have used ultra-thin layers of 2D structures known as metasurfaces to create holograms that can measure the polarization of light. The new metasurface ...

Researchers have demonstrated a new compact spectroscopic instrument that offers a highly sensitive optical method for detecting radiocarbon dioxide concentration, which can be used to carbon date ...

A European collaboration has used one of the world's portable optical atomic clocks to measure gravitation for the first time. A European collaboration involving clock experts from the National ...
