Gentec-EO – Laser Power Meter & Laser Energy Meters

TECHNICAL SHEET

Gentec-EO’s QPM Series is a fully automatic laser power probe that calculates laser power by measuring temperature dynamics using a microprocessor. Its measurement and acquisition technique determines the time needed to carry out a measurement. Data acquisition is triggered and stopped by detecting set heat parameter thresholds. This technique is virtually error free and allows for multiple measurements without absorber forced cooling.

Six models cover the full-scale powers from 500 mW to 10 kW. Their innovative measurement concept cuts the time to measure and display down to ten seconds on all probe models providing:

Excellent accuracy (± 3 to 4%)

Repeatability (± 1 to 2%)

High resolution

The QPM features a large multifunction LCD that simultaneously indicates:

Measured power

Actual accuracy

Calibration wavelength (CO₂, Nd-YAG, Diodes)

Maximum power range

Low-battery warning

Probe model

A bar graph shows the actual absorber temperature, which informs the operator that he can still make measurements before the absorber reaches its maximum temperature. Additionally a two colour LED indicates the probe status: probe is ready (steady green), measurement is in progress (flashing green), measurement is over (steady red) or cooling is needed (flashing red).

A single button operates the QPM. It turns off automatically after five minutes of non operation. When your turn it back on you will see the last measurement. Two AA batteries allow a minimum of 4,000 to 5,000 measurements.
