NEWPORT 325 2.5 A Temperature Controller

The Newport 325 Temperature Controller provides superior temperature stability and a wide range of power output. It has a fast settling, hybrid P-I control loop that delivers a low noise, bipolar current output in three operating modes: 1) constant R (thermistor), 2) constant T (IC sensors), or 3) constant ITE . A user adjustable ITE current limit setting unconditionally protects the TE modules from damage by excessive drive current independent of the operating mode. The Model 325 is compatible with thermistors, and AD590 and LM335 Series IC temperature sensors. Temperature readings (°C) are displayed when using one of these IC sensors. Specifications.

*This is a Web introductory price for one calibration of the NEWPORT 325. 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.

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth
Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
