Newport 505B Laser Diode Driver
The Newport 505B Laser Diode Driver is a precision current source instrument module that operates in constant current or constant optical power modes. Its configuration supports industrial automation platforms that require tightly regulated laser power for repeatable processes. This module supplies output current from 0 to 100 mA and its output resolution is 2 microamps while its accuracy is recorded as 0.5%. The 505B laser diode driver possess compliance voltage of 7 V and its short-term current stability is better than 10/1000000 of full-scale hourly. Its long-term stability remains more than 50 ppm of full scale over 24 hours total. These stability characteristics allow extended unattended production runs with minimal drift of laser operating conditions.
Its selectable bandwidth control optimizes modulation speed or output noise performance for the driven laser diode. Its high bandwidth setting supports modulation from direct current to 600 kHz for dynamic control while low bandwidth setting limits modulation to 10 kHz and minimizes root mean square output noise. The external analog modulation input of this Newport 505B laser diode driver accepts 0 to 10 V into a 10000-ohm programming impedance. Its transfer function is 10 mA/V exactly. This interface enables straightforward integration with programmable logic controllers and motion controllers in automated systems. Its monitor photodiode input measures currents from 0 to 5 mA with 1 microamp resolution with monitor current accuracy 0.05% of full scale. The provided adjustable photodiode bias from 0 to -5 V optimizes detector linearity and response characteristics.
The unit’s panel display reports laser drive current and monitor photodiode current during configuration and operation. Its displayed laser current range extends to 100 mA with resolution suitable for fine operating adjustments. The displayed photodiode current range extends to 5 mA enabling accurate observation of optical output stability. Its input power compatibility includes nominal 100 to 240 V mains supply ranges. The 505B module permits mains frequency range of 50/60 Hz to match standard industrial distribution networks worldwide and its maximum power consumption is 30 W for. This unit possess mechanical dimensions of 3.5 x 8 x12 inches (88.9 × 203.2 × 304.8 mm). Its mainframe weight is 84.04 kg (8.9 lbs.) and its safety functions include a key operated laser enable control and interlock loop for system protection. Its dedicated connectors separate laser diode outputs monitor photodiode terminals and modulation inputs to simplify wiring.
