Features

1 Hour Temperature Stability

One hour temperature stability measurements performed in a typical lab environment, on a Newport laser Mount 764H-110 with an Oclaro BW-series laser running at 10W optical output power. Ambient temperature variations during the test period of the order of 2 °C is shown. The Laser mount temperature was set at 21 °C for the entire test over a 1 hour period and was held stable at 21 °C with a variation of ± 0.0004 °C over the 1 hour period.

24 Hour Temperature Stability

24 hour temperature stability measurements were performed in a typical lab environment, on a Newport Laser Mount 764H-110 with an Oclaro BW-series laser running at 10W optical output power. The graph displays ambient temperature variations during the test period of the order of 3 °C. The laser mount temperature was set to 21 °C with a variation of ± 0.00077 °C over the 24 hour period.

High Power Laser Diode Control Kits

When it comes to selecting a laser diode mount and diode driver to go along with your new temperature controller Newport does all the work for you. Our newly introduced laser diode control kit (LDKIT series) bundles the diode driver, temperature controller, mount, cables, grounding wrist strap and thermal paste compound all at a great price.

The LDKIT-80A-110W includes 5700-80-7 driver, 3700 temperature controller, 764H-110 mount, cables, thermal paste and grounding wrist strap. Laser diode not included.

Full Current Output Across Compliance Voltage Range

Innovative hardware and firmware design allows 3700 to output 14 A over the full 0-24 V compliance range. Compare this with our competitors’ controllers output capability shown.

Advanced PID Control

PID control is implemented in the Model 3700 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. Protection features include: ITE Limit, Hi and Lo Temperature Limits, Voltage Limits, Sensor Open and TE Open Detection. To prevent noise pickup, either by the output lines or the sensor inputs — resulting in undesirable temperature oscillations — shielded cables are also available.

Multiple Supported Temperature Sensors

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.

4 Line x 20 Character LCD Display

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.
