LaserStar
Versatile Laser Power/Energy Meter
• Two models available: dual and single channel
• Single channel model can be upgraded to dual channel
• Compatible with all standard 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 59,400 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
• GPIB option (IEEE488.1)
• NIST traceable • CE marked
• Soft keys, menu-driven
The LaserStar's dual channel capabilities enable the user to simply plug in any of Ophir's thermal, pyroelectric or photodiode sensors and measure the two channels independently, or a comparison between the two channels. 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.
