Part 2 of this article continued the exploration of the basic optical tweezer. This part builds up to a complete system, DIY optical tweezer systems, and extensions to the basic optical-tweezer arrangement. The optical tweezer is obviously not a simple system, and a complete system requires lenses, dichroic mirrors, a laser, video camera, isolation against […]

Optical tweezers move nano-objects, Part 2: The optical path
A combination of optics, lasers, electronics, and combined with advanced physics principles, allows “touch-free” physical manipulation of molecules, viruses, and other nano-sized objects. Part 1 of this article presented the goals of the optical-tweezer design and some of the reasoning which leads to it. This part continues to build up to a larger, complete system. […]
Optical tweezers move nano-objects, Part 1: The Principles
A combination of optics, lasers, electronics, and combined with advanced physics principles, allows “touch-free” physical manipulation of molecules, viruses, and other nano-sized objects. How do you manipulate and move tiny objects such as pieces of DNA or living cells? Conventional mechanical or vacuum tweezers, no matter how small, couldn’t grab them and would cause damage […]
Glass-reinforced thermoset now available in multiple thicknesses
Wireless circuit designers can now enjoy a true breakthrough with Rogers Corporation’s RO4450T bondply. This product offers designers a spread glass reinforced bonding material in seven thickness options ranging between 0.0025” (0.064mm) and 0.006” (0.152mm), greatly improving flexibility for high multilayer board count designs. RO4450T glass reinforced thermoset bondplies were developed for wireless circuit designers […]

The MAX31825 digital […]
Sockets enable fast swap-out of BGA devices for development sorting, failure analysis
Grypper sockets for BGA components used on Memory cards are great for enabling fast swap-out of BGA devices for development sorting and failure analysis. The Grypper socket allows operators to simply snap-in the BGA device – No Lid needed. The Grypper sockets are the same size as the device, so they will reflow directly onto […]
Smallest SMD oven-controlled crystal oscillator hits 40 MHz
