P-9710-1 – Multi-functional light meter for high-quality photometric measurements
The P-9710-1 optometer is a high-quality device designed by Gigahertz-Optik for mobile use. Its signal amplifier provides a wide dynamic range for the detectors’ signal currents ranging up to 2 mA. The noise-equivalent current signal is as low as 0.1 pA. The device has eight gain ranges that can be manually or automatically selected for adjustment to match the signal levels.
Variable integration time
One of the characteristic properties of the P-9710-1 optometer is the short integration time of the input amplifier that only ranges around 100 µs. This enables reduction of signal noises through multiple measurements with averaging. The 100 µs integration time also makes it possible to perform many other measurement functions:
- Adjustable integration times in CW measurement mode
- CW measurement with noise proportion (peak-to-peak)
- Peak value measurement
- Pulse energy measurements of short light pulses
- Dose measurement
- Fast data logger for up to 12000 measurement values
Photometer, radiometer, UV-meter, laser-intensity-meter
For use as optometer the P-9710-1 can be combined with all offered detector heads intended for photometric and radiometric measurements. The plugged detector head determines the photometric or radiometric measuring size as well as the spectral range of the measurement. Gigahertz-Optik offers a wide range of detector heads for various measuring tasks. The optometers’ signal input amplifiers offer a very wide dynamic range, in order to adjust the devices to detectors with various sensitivities and optical radiation intensities. The calibration data of the detector heads are saved in the calibration data plug of the detector heads.
Simple and safe detector exchange
Upon attachment of a detector head with a calibration data plug onto the P-9710-1 optometer, its calibration data as well as the device settings are automatically applied. This ensures that improper operation that might result from exchange of measurement heads is basically ruled out.
The P-9710-1 optometer can be connected to a PC via its RS232 interface.
Light measurements and light analysis
The P-9710-1 optometer has eighteen different measurement modes that can easily be selected using a user-friendly menu hence enabling its multifunctional application.
P-9710-2 – Optometer for dose measurement of short pulses using the pulse stretching method
Unlike the P-9710-1, the P-9710-2 optometer has a 20 ms standard time constant in all eight gain ranges. Thus light pulses shorter than 1 ns are stretched to 20 ms. The pulse energy of the stretched pulse can then be measured precisely with the 100 µs sample rate of the optometer.
P-9710-4 – multi-functional light meter for synchronized measurement of short light pulses
Similar to the optometer P-9710-2, the P-9710-4 also has a 20ms standard time constant in all eight gain levels. Besides the manual start of via keyboard, the dose measurement can also be started remotely via the trigger input.
The P-9710-4 offers a trigger input for a remotely controlled triggering of measurement
The optometers P-9710 provide connections for power supply, detector heads with calibration data plug and a RS232 interface (from left to right).
