An achromatic linear polarization rotator based on a tandem-2Ï•-twisted nematic liquid crystal cell (tandem-2Ï•-TNLC cell, where 2Ï• represents the total twisted angle) is theoretically analyzed and ...
To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are ...
Roller-pinion systems are a better option than rack and pinions where accuracy and a minimum of friction are important. • Roller pinions can provide accurate positioning up to ±30 µm (±0.00118 in.) • ...
Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.
OTTO is an open-source automated liquid handler that can be fabricated at a cost of $1,500 using off-the-shelf and 3D-printable parts as an alternative to commercial devices. Open-source approaches ...
Monitoring takes the form of sensors and intelligent devices connected to a digital processor. These monitored values are used for computing and then controlling some sort of real-world action. Many ...
