Description
The Gentec-EO QE series is a robust line of high performance and high accuracy pyroelectric joulemeters that are designed to measure laser energy. Each modular unit is built for durability, compactness and ease of operation.
The QE optical absorber exhibits high damage thresholds and can operate at high rep-rates. The QE series can be used to even higher energy levels with QED attenuator / diffuser.

Features
The QE series benefits from the use of a DB-15 male, “Smart Interface” connector, containing a memory chip programmed with the calibration sensitivity, the spectral correction factors at different wavelengths and other data relating to the specific Q series joulemeter head. This connector permits the Gentec-EO display or PC interfaceo automatically adjust to the characteristics of the joulemeter being connected.
All QE series detectors are also available with the INTEGRA connector. This option only needs a computer or tablet PC using the free software PC-GENTEC-EO. It is also programmed with the calibration sensitivity, the spectral correction factors at different wavelengths and other data relating to the specific QE series joulemeter head. The INTEGRA options are USB, RS-232 or USB with external trigger.
Every QE series joulemeter features high intrinsic responsivity and high insensitivity to electromagnetic interference.
The QE series also offers an exceptionally wide dynamic range and permits energy measurement from UV to far IR.
The QE series joulemeters are also available as custom products with analog output to be used with an oscilloscope or an OEM acquisition system.
Applications
- Laser energy measurements
- Laser optics
- Spectroscopy
