New Products for the Week of Nov. 27, 2000

TEC source meterThe Model 2510 TEC Source Meter is designed for test and control of the TEC portion of laser-diode modules. The Model 2510 features a 50-W source and a software-based, digital temperature-control loop, with typical stability to within ?0.005?C of set point. The Model 2510 supports a variety of temperature sensors. Four-wire source/measure for thermistors and RTDs enhance measurement accuracy. An ac ohm function has been incorporated to enable more accurate testing of the TEC Peltier heater/cooler. The unit is warranted against defects in materials and workmanship for one year and carries the CE mark.Keithley Instruments, Cleveland, OHPhotodetectorsThe MXP3000 series of gallium arsenide photodetectors is designed for fiberoptic transceiver modules and hybrids in the 850-nm range. The devices offer dark current ratings of 1 to 3 nA and a breakdown voltage of 20 V with the bandwidth options for 1.4 to 8.75 GHz, depending on an active area ranging from 250 to 30 mm².Microsemi Corp., Santa Ana, CACCD detection systemsA variety of detection systems include front- and back-illuminated CCDs with a choice of pixel sizes. Readout rates range from 100 kHz to 5 MHz, and detector heights range from 2 to 12 mm. Coatings are available to boost quantum efficiency, and deep-depletion devices can provide higher sensitivity in the NIR.Roper Scientific, Tucson, AZNd:YAG laserThe Solo PIV Nd:YAG laser measures 14 x 6 x 3 in. and is designed for particle image velocimetry applications. The Q-switched laser comes in four models, with output pulses of 15 to 50 mJ at (532 nm, repetition rates of 1 to 15 or 1 to 30 Hz, and beam diameter of 2.5 or 3.5 mm. Pulsewidth is 5 to 7 ns (FWHM), and energy stability is ?4%. New Wave Research, Fremont, CA
