Please note that 8000-OPT is obsolete. Instead, users are advised to order Model 8000 Mainframe and modules separately. Once the modules are plugged in the bays, the instrument is ready for use.
The Model 8000 Modular Multi-channel Diode Laser Controller mainframe automatically detects which module is located in each of the four fully isolated bays available, and displays the entire system configuration on the large LCD display. After the 8000 has detected your module 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 Multi-channel Laser Diode Controller is a cost effective solution that meets your laboratory, production, and quality control applications. Our flexible system design guarantees that the Model 8000 is the most complete and robust instrument for laser diode control, characterization, and testing.
The Model 8000 mainframe and the modules are not CE compliant.
In addition to the modules shown in the table, we have additional obsolete modules available on clearance sale. Please check Newport's search web pages.

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.
Temperature controllers may be operated in one of three modes:
a. Constant temperature
b. Constant resistance (thermistor and RTD), LM335 Voltage, or AD592 current
c. Constant TE Current
Short-term stability is better than 0.0005°C while long-term stability is better than 0.001°C.
Four sensor types are available: thermistors, AD590 Series, LM335 Series, 100Ω Platinum RTD’s. 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.
Newport's temperature controllers have unparalled long-term stability of better than 0.001°C
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.
Combination LDD/TEC Modules
When temperature stabilization is required, the 8600 Series Combination LDD/TEC modules give you full control of your laser diodes. A 15 W (2.5A/6V) TEC section is combined with a quiet current source for complete stabilization of your laser diode.
A single 8600 module is capable of providing the necessary control for wavelength tuning laser diodes. The TEC section is used for coarse tuning while the LDD section is used for fine tuning. The Model 8000 is capable of precision wavelength tuning due to the fine resolution capability resulting from 16-bit control technology.
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. Both sinewave or squarewave (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.
Whether you are wavelength tuning your laser diode or require full characterization capabilities, the 8600 Series combination LDD/TEC modules provide complete control of your laser diode.
Comprehensive Safety Features Protect Your Laser Diode Investments
Time tested safety features are incorporated into the Model 8000 mainframe and each laser diode driver module to provide maximum protection to your laser diode. Input power module filters provide first stage protection against AC line transients. Secondary filtering and power regulation stages coupled with high speed transient detection circuits and a proprietary intermittent contact protection circuit are added resulting in the most sophisticated laser diode instrumentation available today. All this in addition to 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.
Intuitive Controls and Large Graphics Display Simplify Control and Test Procedures
Improved data presentation and system control is achieved by using large graphics display. The MASTER screen presents the entire system configuration as well as each module’s status as “Soft Keys” guide you through initial system setup routines and operation of each module.
Real-time control of an output is accomplished either by entering a set point on the keypad or on the digitally encoded control knob. The “Soft Keys” access saves system configurations and repetitive procedures. User-defined mini-programs and control functions are entered using the "FUNC" key, giving you maximum flexibility when using the Model 8000.
All controls are clearly marked, and instructions easily defined. The Model 8000 Modular Controller lets you work with laser diodes easier and faster than any other controller on the market today.
Limiting circuitry unconditionally prevents laser diode current from exceeding limit setting independent of operating mode even during external analog modulation.
