Gigahertz-Optik Introduces UV-VIS-NIR Pulsed Light Meter with External Trigger Input

Gigahertz-Optik’s hand-held P-9710-4 radiometer/photometer now features an external TTL trigger input function useful for remote timing of pulsed light measurements. In the P-9710-4 pulse energy mode, the measurement begins automatically upon the trigger input.

The P-9710-4 is capable of measuring the pulse energy (joules, J/cm2, lux-seconds, effective candela) of single and multiple burst pulsed events >1 microsecond in length. Stepped auto-ranging allows the user to zoom-in on the correct gain level with the last setting stored for future use. Independent of signal magnitude, system bandwidth is 0.166 Hz (at 6s) to > 300 MHz within the unit’s current measurement range of 0.1 pA to 2 mA.

Fifteen other menu selectable modes of operation including CW, dose, RS232 remote control plus internal datalogger function and AC or rechargeable battery power qualify the compact P-9710-4 for laboratory or field use.

Other key features include adjustable sampling time (100 micros to 6 s) and continuous offset of the pre-trigger light level as well as computation of luminous effective intensity based on selectable standard methods.

All essential detector data is stored in the detector’s data coupler so that any number of sensors with associated components like optical filters, integrating spheres and other input devices can be interchanged on the optometer for error free system set-up.

A wide range of UV-Vis-NIR detectors is available specifically configured for light measurement applications like intensity of medical flash heads and effective luminous intensity of strobe light warning signals or the radiant energy of pulsed Xenon sources used in UV Curing and UV processes.
