Temperature Controller utilizes PID control loop.

August 24, 2004 - Series 300B laser diode temperature controllers utilize PID (proportional, integral, derivative) control loop, which provides ±0.005°C control of laser temperature over -50 to +150°C temperature range. Operating temperature is selected through front panel controls or via USB interface for remote reading and control. Model 325B delivers max current of 2.5 A, while 350B provides up to 5.0 A. Each offers closed-loop control and 3 modes of operation.

New Diode Laser Temperature Controllers Offer Exceptional Performance

Irvine, California â€“ August 20, 2004 â€“ The new 300B Series laser diode temperature controllers from Newport Corporation offer an unmatched combination of features, performance, and value. In particular, these are the first low-cost temperature controllers to utilize Newportâ€™s innovative PID (proportional, integral, derivative) control loop. This provides extremely tight control (±0.005°C) of laser temperature over a broad ambient temperature range. Operating temperature for these new instruments is selected through intuitive front panel controls. They can also be configured using the standard USB interface to permit external control of temperature set point, PID loop parameters and to allow system status and to be read remotely.

The 300B series diode laser temperature controllers offer lower noise and greater temperature stability than any other controller in their price range. This enables them to cost-effectively support demanding applications in scientific research and spectroscopy, as well as fiber optic communications research, development and testing.

Two different 300B series temperature controllers are available. The Model 325B delivers a maximum current of 2.5 A (17.5 Watts), while the Model 350B provides up to 5.0 A (55 Watts). Each offers precise, closed-loop control of a thermo-electric cooler (TEC), and is compatible with thermistors and a number of IC type temperature sensors. Both models enable temperature to be set over the -50°C to +150°C range, with a resolution of 0.1°C and an accuracy of ± 0.1°C. Each offers three different modes of operation: constant thermistor resistance, constant temperature (for IC type sensors) or constant TEC current.

More information on Newport's comprehensive line of diode laser instrumentation is available on the companyâ€™s web site at www.newport.com/controllerspr.
