There is no replacement for in-person events, says Carlos Lee, but there are many reasons to be cautious

In deflectometry, a camera images fringe patterns that have reflected off a surface under test, so that a system can deduce a map of the surface slopes from the deviation of the projected fringes, and from that determine the surface shape. Credit: Mahr

Lens features have been getting too small to properly characterise – but metrology providers are catching up, finds Andy Extance

Focuslight technologies, a global provider of high power diode lasers and micro optics, announced the LIMO Wide Angle Diffuser at SPIE Photonics West 2020. Designed for automotive LiDAR and 3D sensing applications, the LIMO Wide Angle Diffuser is a glass refractive optical element (ROE) with the ability to disperse laser light in one direction up to a full illumination angle, ranging from a few mrad up to 150 degrees. When combined with a second functional surface, the light can also be shaped at any desired angle in the other direction.
