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.
