The Model 6100 laser diode and temperature controller speaks of unmatched precision current and temperature control. The unit features a 500 mA/1,500 mA current supply range and a 32W temperature controller. Its design exploits DSP-based PID control to achieve a less than 0.001°C temperature stability and a 1.3 µA ripple figure. Other features include a four-line alpha-numeric menu system, two seven-segment displays, and a fast LIV measurement function. NEWPORT CORP., Irvine, CA. (800) 222-6440.
