The Model 3150 Temperature Controller provides a 350 W bipolar output for operation with thermoelectric (TE) coolers. Active power management of the output DC power supply reduces unnecessary power dissipation resulting in increased temperature stability and higher reliability. Full 16-Bit control and characterization of the TE module and temperature sensor is attainable via the IEEE-488 or RS-232 interfaces. All pertinent TE cooler parameters ITE, VTE, temperature sensor (°C, R, Amp, or Volts) are measured and simultaneously presented on the four line alphanumeric LCD display. All standard temperature sensors including thermistors, platinum RTD, AD590/592 and LM335 IC sensors are supported without the need for additional interface units. Sensor calibration constants are easily programmed for direct readout in °C. A proportional-integral (P-I) control circuit is implemented in the Model 3150 that meets all the temperature stabilization requirements for laser diode users. During operation, the front panel controls can be disabled to prevent any changes in the output by accidental misadjustment of the control knob.

Modules 8605.16C and 8610.16C:
The 8600C Series Combo LDD/TEC modules are designed for use in communication applications and have an internal function generator for testing systems. The user only needs to program the frequency, Imax, and Imin to modulate the laser diode output. Triangle, sine or square (50% duty cycle) waveforms are available from 200 Hz-300 kHz. This range of frequencies meets today's low frequency single-tone and high data rate test requirements for datacom and telecom.

Module 8350:
A 40 Watt Temperature Controller Module, the Model 8350, can meet your most demanding TE cooling needs. Complete characterization of ITE, VTE and the sensor input is possible, making the 8350 module ideal for complete characterization of telecom laser diodes.

The Newport 5600 High Power Laser Diode Drivers feature advanced circuit designs and careful layout of laser diode drivers to provide you with an extremely low noise, highly stable output current. External analog modulation input allows precision control of the laser output for a variety of applications including power level control and wavelength tuning. A monitor photodiode is reversed biased at 5 Volts. All laser diode parameters are accessible with 16-bit resolution including the laser diode's forward voltage for full characterization.
Time tested laser diode protection safety features are incorporated into the 5600 Series Laser Diode Drivers. Input power module filters provide first stage protection against transients. Additional filtering and power regulation stages coupled with high speed transient detection circuits let you operate your laser diode worry-free from transients. A slow turn-on sequence, multiple output shorting circuits, and an independent current limiting feature provide the superior protection you demand from all your laser diode instrumentation.
