Gatan MonoCL3+


Cathodoluminescence registration system Gatan MonoCL3+ is equipped with precise parabolic mirror and two high sensitivity detectors which make one able to record CL spectra in a wide range of wavelength from ultraviolet (UV) to near infrared (NIR).

For spectra acquisition in 900 nm - 2000 nm wavelength range (NIR) the LN2 cooled InGaAs CCD-array Princeton Instruments/Acton IRCL-9 is used. It has 1024 elements of about 2 cm total length. Such setup implements spectrum Parallel acquisition that in turn gives a lot of advantages main of which is precise measurement of peaks relative position.

The system includes the continuous flow liquid helium (LHe) cryo-stage that could also be coold with LN2 (Dual-fuel option).

The list of Gatan SEM analytical tools is extended with SmartEBIC system for Electron Beam Induced Current registration (EBIC). For Current registration Stanford Research SR570 amplifier is used.
