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.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence
Coherence is the pattern and or relationships of waves due to phase properties.

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.
