P-2000-2 Optometer
ISD-30P-SiIGA-2 Laser Power Integrating Sphere Detector

The highly efficient two-channel P-2000-2 optometer in combination with the ISD-30-SiIGA-2 detector forms a measurement instrument for laser diode driven range finders and large beam diameter lasers in the wide wavelength range from 400 to 1800nm. The ISD-30-SiIGA-2 is built with a 300mm diameter integrating sphere with 100mm measurement port. Two photodiode detectors one silicon and one Indium Gallium Arsenide enable wavelength range coverage from 400 to 1800nm. The sphere with both detectors is calibrated for spectral radiant power sensitivity in W from 400 to 1800nm in 10nm wavelength steps. The calibration is traceable to international standards. The two-channel P-2000-2 optometer processes and displays both ISD-30-SiIGA-2 detector signals. It features an amplifier configuration optimized with gain range independent rise time for CW measurement as well as the measurement of short light flashes, pulse chains and pulse bursts by the pulse stretching method. The compact size bench top housing meter includes a four-line blue back-lit display. A unique feature of the P-2000 is its detector head calibration data connector which stores all data pertaining to a light detector head including model and serial number and calibration data. When plugged into the meter, this data is automatically transmitted and the light meter is ready to go. This feature allows the P-2000 optometer to be used with an unlimited range of light detectors combined with more than sixteen functional measurement modes enabling the user to specify light sources in different ways. This includes ratio measurements between the two measurement channels. The P-2000’s wide signal range of 0.1pA to 2mA with eight manually or automatically selected gain ranges covers the dynamic range of most current semiconductor photodiodes used in light detector heads. The maximum error within this wide dynamic range is 0.2 % through traceable calibrations of each range. A bi-directional RS232 serial interface and GPIB bus interface (IEEE488) allows external remote control. Optional PC software is available. The meter is DC low voltage operated with external AC power supply.
