Diode laser arrays. Using proven and robust fiber bundle technology, a new line of diode laser arrays is announced with a brightness improvement that -- with 90% of the power in a 0.12 numerical aperture -- allows delivery of up to 60 watts of output power. The enhanced brightness of the fiber-coupled FB Series affords increased power density and depth of focus, two primary requirements for many industrial, medical and solid-state laser-pumping applications.

Level transmitter. The Model UT125 Ultrasonic Level Transmitter provides noncontact measurement for liquid level control by generating an ultrasonic pulse in vessels. Its range of 10 ft. is accurate to ±0.25% and generates a 4 to 20 mA output signal that is updated every one-half second. It features height and distance mode adjustment, lost echo LED indication and reverse polarity protection.
