OL 410 Precision Lamp Sources The OL 410 is a microprocessor-controlled, precision DC lamp source specifically designed to accurately operate tungsten filament lamp standards and calibration sources. The power output range is 150 watts for the OL 410-150 and 200 watts for the OL 410-200. Both units feature: • • • • • • • Output current accuracy of ±0.02% or better Controlled ramp up / ramp down of the lamp current Simultaneous digital readout of lamp current, voltage, and power Ten (10) element lamp library with individual lamp hours monitors Large two-line display with ON/OFF control Adjustable tilt handle Full-speed USB 2.0 interface Tungsten lamp standards must be operated at their specified calibration current in order to realize the accuracy of the standard. A small error in setting the lamp current can induce a sizeable, wavelength dependent error in the spectral output of the lamp. The OL 410 enables the lamp current to be set to an accuracy of better than ±0.02%, a factor of about 12½ better than most other commercial power supplies, which are typically 0.25%. The advantage of the OL 410's increased accuracy is illustrated in the table. In order to eliminate electrical shocking of the lamp due to high initial current surges, a ramp function is used to control the turnon current rise. Once the instrument is turned on, the current automatically increases at a slow, safe rate until the set current is reached. A fail-safe, shut down circuit protects the lamp standard against any equipment malfunctions. OL 410 improvements over the OL 65A Programmable Current Sources include: • • • • • • • User-configurable line voltage Pre-regulator eliminates the range switch, thus allowing a wider range of lamps (not available on the OL 410-150) Three point calibration for better accuracy at low currents USB interface instead of RS-232/ GPIB New .NET software development kit and application Enhances reliability due to improved heat sink and single output transistor More stable due to improved drive electronics SPECTRAL IRRADIANCE UNCERTAINTY Due To ERROR IN SETTING LAMP CURRENT Wavelength (nm) The current sources will maintain their accuracies while experiencing ±10% fluctuations in line voltage and ±10% variance on the load voltage. These features effectively compensate for transients in the power line and variations in resistance from one lamp to another.
