Rotary position sensors *
A manufacturer of linear and rotary sensors has introduced a new series of contactless, fractional-turn rotary position sensors.
The RSE 1500 Series Rotary RVDT Position Sensors, made by Macro Sensors, measure the angular displacement of rotating elements, such as quarter-turn ball and butterfly valves, air flow dampers, mail sorters and diverter gates used in packaging and postal sorting machinery.
The sensors use a 24-volt DC power supply and can measure shaft angle position over a nominal range of 120°. They exhibit linearity error of less than 0.10% while operating at temperatures between 0° to 185° F.

Tunable laser systems *
A new series of tunable laser systems has been released by Opotek. The Opolette HR series features highly stable, integrated tunable laser systems that use a diodepumped, true solid state laser as the pump source.
The systems operate at high repetition pulse rates of up to 100 Hz. components are mounted on a hermetically sealed optical bench. System functions, including laser operation, wavelength tuning, and scanning, are controlled by computer through a USB connection.
System uses include medical diagnostics, chemical imaging, environmental monitoring, photobiology, photochemistry, photoacoustic imaging and proteomics.
