Luminary Ultrafast TEM / Dynamic TEM

The Luminary time-resolved transmission electron microscope is designed for pump-probe experiments using one or more lasers to study transient phenomena in specimens.
Users can directly excite the sample with a laser and generate photoelectron probe pulses with a UV laser to probe the sample in imaging, diffraction, spectroscopy, or spectral imaging modes. The Luminary time-resolved TEM is an extremely versatile platform that allows users to choose their optical configurations with a multitude of laser types to conduct ps stroboscopy, ns stroboscopy, ns single shot (SS), and/or ns movie mode (MM) measurements, as well as conventional thermionic mode, in a single instrument.
The Luminary time-resolved TEM is based on a 200kV TEM JEM-2100Plus and is modified to introduce laser beams directed toward the cathode (electron source) and the sample, including laser optical systems as standard and the laser(s) as options.

Relativity Electrostatic Subframing System

The IDES Relativity Electrostatic Subframing System multiplies the frame rate of cameras on JEOL TEMs.
Microscopes equipped with Relativity achieve exceptional time resolution, data throughput, and advanced automation capabilities.

Electrostatic Dose Modulator (EDM)

The Electrostatic Dose Modulator (EDM) is a fast beam blanking system with a pre-sample electrostatic deflector, including electronics and software control. With EDM, the beam can switch on or off in less than 50 ns. This 100,000x improvement in blanking speed immediately improves the clarity of data taken at fast exposure times. EDM can also attenuate electron illumination without affecting imaging conditions, giving TEM and STEM users exceptional control over the dose on their samples. Cutting-edge electronics and software add-ons unlock advanced applications such as temporal dose structuring and STEM synchronization.

How dose Relativity work?

Relativity installs an electrostatic optics assembly in a wide-angle camera port. These optics rapidly deflect the image data to different regions (or subframes) of the camera in a programmable sequence. Each camera readout contains a tiled array of crisp, blur-free subframes. Raw data is automatically analyzed to give a stack of images.

Electrostatic Dose Modulator (EDM)

  • Lightning-fast speeds:
    EDM systems achieve switching times faster than 50 ns.
  • Independent intensity adjustment:
    By rapidly turning the beam on and off with variable pulse widths, the EDM makes it easy to adjust the average beam intensity without changing the image conditions. A desktop accessory knob provides an intuitive interface to adjust the dose attenuation factor.
  • Dose structuring:
    Users can take control of their illumination by applying dose in pulses with variable durations as short as 100 ns and frequencies up to 1 MHz.
  • Modern control software:
    The EDM works out of the box as a fast beam blanker. Control software is included for programmable dose attenuation, logging, and more.
  • Integration:
    The EDM act as a fast reliable pre-sample beam blanker while supporting a companion Relativity Sub-Framing System as well as third-party hardware.
