NEWPORT 3700 14 A / 24 V High-Power Thermoelectric Temperature Controller

The Newport 3700 TEC Controller provides a 336 W bipolar output for operation with thermoelectric (TE) coolers and replaces legacy Model 3150. At the unit's heart, DSP based controls allow for PID settings with fast settling times. Computer interface is possible via a USB terminal. All pertinent TE parameters, ITE, VTE, temperature sensor (° C, R, Amp, or Volts) are measured and 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 an additional interface needed. Sensor calibration constants are easily programmed for direct readout in ° C. Protection features include: ITE Limit, Hi and Lo Temperature Limits, Voltage Limits, Sensor Open and TE Open Detection. Specifications. TE Current: -14.00 to +14.00 A . TEC Short-Term Stability (1 h): 0.0009 °C. TEC Output Long-Term Stability (24 h): 0.0019 °C . TEC Ripple/Noise (rms): <1 mA. ITE Current Resolution: 1 mA. Output Power: 336 W. Temperature Coefficient: < 0.0005 °C/°C. TEC Current Limit Accuracy: ± 0.3 % FS. Display Controls: Brightness, contrast (optimizes viewing angle). Display Type: 4-line by 20 character alphanumerical, and seven segment display. Display Backlighting Green LED.

*This is a Web introductory price for one calibration of the NEWPORT 3700. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength
Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
