505B In Stock

The 505B by Newport is a Laser Diode Driver that can be utilized for high-demand applications such as fiber optic communications, spectroscopy, and those necessitating a consistent and stable optical power output from a laser. Boasting a current capacity of 500 mA, this driver ensures both electrical low noise and reliability. The 505B driver provides the flexibility of operating in two distinct modes: constant laser power mode and constant current mode. This dual-mode functionality empowers users to meticulously tailor the current resolution settings, optimizing output to the laser diode with precision. Incorporating a redundant FET and relay shoring circuits, the driver safeguards the laser diode during the gradual turn-on sequence, ensuring user protection during operation.

The 505B offers dynamic voltage or output modulation, conveniently controllable via external analog modulation. This capability enables users to finely modulate laser output, facilitating low-power control and wavelength tuning through electrical control circuitry. This results in superior noise reduction, thus facilitating precise laser output power control. Navigating the 505B is facilitated through its user-friendly front panel, organized into seven distinct sections, each dedicated to a specific set of functions. Featuring a control knob, this interface includes an interlock feature accessible through the front panel key switch. Furthermore, connectivity is extended through the USB 2.0 connector on the unit's rear, enabling seamless computer integration. Ease of installation is further enhanced by the unit's rack-mount compatibility. Designed for standard rack configurations, this driver can be conveniently mounted side by side using compatible screws and brackets. Notably, the unit accommodates a monitor photodiode, offering reverse biasing within the 0-5V range without requiring an external power supply.
