All you do is follow on-screen instructions to configure and operate the modular system. Advanced 16-bit technology, coupled with careful designs that isolate digital and analog signals, ensure precision control and measurement capabilities. GPIB/IEEE-488.2 and RS-232 interfaces are included with the Model 8000 mainframe for complete remote control and data collection. LabVIEW drivers are supplied with every Model 8000 Modular Controller. The Model 8000 Modular Controller is a cost effective solution that meets your laboratory, production, and quality control applications. Our flexible system design guarantees that the Model 8000 will accommodate future modules - making it the most complete instrument for laser diode control, characterization, and testing far into the future. • Comprehensive laser diode protection features • Large graphics display, allowing full four-channel visibility • Complete laser diode characterization (L, V, I) using 8500 modules • Complete TE cooler characterization (ITE, VTE) using 8350 module • Standard GPIB/IEEE-488.2 and RS-232 interface Controller Modules Temperature Controllers We offer a 40 W Temperature Controller Module, Model 8350, for Model 8000 to meet your most demanding TE cooling needs. Complete characterization of ITE, VTE and sensor input is possible - making the 8350 module ideal for complete characterization of telecom laser diodes. We also offer a dual output temperature controller, Model 8325D. It features two independent 15 W outputs that provide the same stability as the Model 8350. Temperature controllers may be operated in one of three modes: a. Constant temperature b. Constant resistance (thermistor and 0 -0.003 -0.002 -0.001 0 Stability (°C) Time (hours) 0.001 0.002 0.003 2 4 6 8 10 12 14 16 18 20 22 24 Newport's temperature controllers have unparalled long-term stability of better than 0.001°C RTD), LM335 Voltage, or AD592 current c. Constant TE Current (8350 only) Short-term stability is better than 0.0005°C while long-term stability is better than 0.001°C. Four sensor types are available: a. Thermistors, b. AD590 Series (8350 only) c. LM335 Series (8350 only) d. 100Ù Platinum RTD’s (8350 only) IC sensors inherently display temperature while thermistors and RTD’s display °C by entering a set of constants. Each sensor can be calibrated to increase its accuracy. A temperature controller can be linked to the LDD module so that the output of the LDD turns off and an error message is displayed if the laser diode temperature exceeds a user-defined operating range. Both THI and TLO are set when configuring the TEC module. An independent ITE current limit protects the thermoelectric module from being damaged by current levels that exceed its maximum rating. Laser Diode Driver Modules Advanced circuit designs and careful layout of the 8500 Series modules results in an extremely low noise highly stable output current source. This coupled with a low bandwidth mode results in the lowest noise output of any modular laser diode system. An external analog modulation input allows precision control of the laser output for a variety of applications. Modulation is available in both constant current mode (ACC) and in constant power mode (APC). A monitor photodiode may be zero biased for CW low noise applications or reversed biased up to 5 volts for high frequency modulation. All laser diode parameters are accessible with 16-bit resolution including the laser diode’s forward voltage. Full characterization of laser diode parameters is available with every current source module offered with the Model 8000 mainframe.
