Module 8350:

A 40 Watt Temperature Controller Module, the Model 8350, can meet your most demanding TE cooling needs. Complete characterization of ITE, VTE and the sensor input is possible, making the 8350 module ideal for complete characterization of telecom laser diodes.

he 505B Laser Diode Driver offers all the performance of the most advanced laser diode controllers for a fraction of the price. Quiet and stable 200 or 500 mA current driver for use in the most demanding applications, such as spectroscopy and fiber optic communications. Intuitive front panel controls make this instrument extremely simple to use. There are two operating modes: constant current or constant laser power.

Dual current-level selection lets you optimize current resolution settings by precisely varying the output to the laser diode. Comprehensive laser diode safety features are built-in including redundant FET and relay shorting circuits to protect the laser diode at the beginning of the slow turn-on sequence. The current limit setting is fully independent.

External analog modulation allows you to voltage-control or modulate the output. USB interface.

The Models 8008, 8016, 9008 and 9016 Modular Controllers expand on Newport's modular laser diode controller concept to meet the higher channel densities found in Dense WDM (DWDM) applications and 2-D VCSEL arrays where all the lasers have similar electrical configurations. The eight or sixteen bays accept an array of LDD, TEC, and LDD/TEC combo modules.

The mainframe automatically detects which module is installed in each bay and displays the system configuration on a large LCD screen. A sophisticated processor provides enhanced system control and data collection capabilities.

GPIB/IEEE-488 and RS-232C interfaces are included with the High-Density Laser Diode Controller Models for complete remote control and data collection.
