1.1.1 General remarks
The thermoelectric Temperature Controller TED200 by Thorlabs GmbH is an
extremely precise temperature controller for laser diodes and detectors.
The TED200 is excellently suited for:
•wavelength stabilization of laser diodes
•noise reduction of detectors
•wavelength tuning by regulating the temperature
•modulation of wavelength by tuning the temperature
The unit is easy to use due to the clearly arranged operating elements on the front
panel. The operating parameters are shown by an illuminated 41/2-digit LCD display,
the measurement value shown is selected via keys.
The gain (P-share) the integral share and the differential share of the PID
temperature control loop can be set free and reproducible.
Different temperature sensors can be used with the temperature controller TED200
(thermistor, or temperature IC sensors: AD 590, AD592, LM135, LM 335). With a
thermistor the temperature display is shown as resistance value in kΩ, if the TED200
is operated with a temperature sensor IC the temperature is shown in °C.
The output for the TEC current can be switched on or off via key from the front panel.
The temperature sensor and the TEC element are connected by a 9-pin D-sub plug
at the rear of the unit.
At the output jack a control signal is available to drive an external LED to indicate
TEC ON mode when the TEC current loop is activated.
