EDM Synchrony - Electron Dose Modulation And So Much More

The Electrostatic Dose Modulator (EDM) is a fast beam blanking system with a pre-sample electrostatic deflector that includes 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 results in immediate enhancement in the clarity of data taken at fast exposure times. Moreover, EDM includes a desktop control knob that allows users to easily attenuate electron dose without affecting imaging conditions. The included software interface gives TEM and STEM users direct access to EDM’s pulse width modulation parameters providing exceptional control over the dose rate on their samples – invaluable feature for beam sensitive specimen imaging and analysis.

Luminary Micro – Precision Localized Laser Heating Without Special Holder

Luminary Micro is a Compact Specimen Photoexcitation System (CPXS) for JEOL TEMs. It is composed of a modulated laser, a compact optical delivery system, an inlet port, and a mirror. With this add-on, users can direct and focus the laser output onto the TEM sample in situ. Luminary Micro can induce a rich variety of reactions and dynamic processes in the specimen, thanks to its <40 μm FWHM focus size, adjustable peak power up to 3 W, and the modulated pulse widths ranging from a few microseconds to seconds. With Luminary Micro, users can study laser-induced phenomena in situ using fast cameras. Combined with IDES/JEOL EDM fast shutter and/or Relativity subframing systems, Luminary Micro allows users to perform time-resolved studies using pump-probe methods in the microsecond time scale. The extremely compact footprint of the system allows easy installation without affecting the TEM resolution. The user can heat specimens to thousands of degrees C while keeping the freedom to use the specimen holder of your choice.

Relativity – High Frame Rate Imaging With ANY Camera

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. Addition of Relativity allows current JEOL TEM users to forego expensive camera upgrades to their existing systems, instead relying on installation of an electrostatic optics assembly in a wide-angle camera port. These optics rapidly deflect the image data to different regions (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 open format images that are loaded back into the camera control software for viewing or further analysis.
