Compatible with all Ophir thermopile, pyroelectric, photodiode and RP sensors ? Large LCD display ? Backlighting and rechargeable battery ? Screen graphics and statistics (std dev. min, max) ? Analog output ? Built-in RS232 interface ? Log every data point at >1500Hz with pyroelectric sensors ? Non-volatile data storage up to 54,000 points ? Laser tuning screen and power log ? Audio sound for laser tuning and low battery ? RS232 interface with StarCom PC application software and LabVIEW driver (see pages 107-109) ? GPIB option (IEEE488.1) ? NIST traceable ? CE marked ? Soft keys, menu-driven The dual channel model enables user to simply plug in any of Ophir’s thermal, pyroelectric, photodiode or RP sensors and measure two channels independently, or the ratio or difference between them in real time. Up to 10 data files (54,000 points total) can be stored for onboard review or downloading to computer even if Laserstar has been switched off. The built-in RS232 interface and StarCom PC software allow on-line processing of data or processing previously stored data; results are displayed graphically on a PC. To support PC interfacing, LabVIEW drivers are provided. Selected Screens Digital Power Screen ? CW industrial, medical and scientific lasers ? pW to multi kW with appropriate sensors ? Can average over selected period. Useful for unstable lasers ? Fast response bar graph Laser Tuning Screen or Power Log Screen (not shown) ? Maximizing laser power ? User selected time period and zoom ?
