Gentec-EO – Laser Power Meter & Laser Energy Meters

TECHNICAL SHEET

The 25 mm aperture of the QE25 is requested for the widest range of applications of any energy detector. It is right for many pulsed lasers. It is right for many OEM, manufacturing and laboratory uses. It has one of the best damage thresholds of any energy detector of its class.

We offer three versions so that you can get the best performance for your application. The short pulse QE25-SP-MT gives you repetition rate up to 6000 Hz but with pulse lengths of up to 10 µs. The short pulse QE25-SP-MB gives you repetition rate up to 800 Hz but with pulse lengths of up to 150 µs. The long pulse QE25-LP-MB is for users who need more pulse width than repetition rate. Also available on special orders, the QE25-ELP-MB for measurement of Extra Long Pulses up to 7 msec, custom-tuned for repetition rate, sensitivity, and pulse width.

The QE25 with heatsink (H) extends performance to higher average powers. You can read all of our Quanta detectors with our SOLO 2 monitor as well as with an oscilloscope.

To extend the performance of the QE25 to higher pulse energies you can select one of our attenuators. For UV applications choose the QEAS-25. It lets you extend the maximum pulse energy by a factor of 2 in the UV. For the highest damage threshold at the longer wavelengths though, you will prefer the QEA-25.
