LEED 800 (model BDL800IR)

Full Flange Size LEED for Higher Angular and Energy Resolution

The LEED 800 with integral shutter has LEED and AES capabilities using a miniature electron gun, set of concentric grids and a conductive, phosphor coated screen. It is an extremely reliable high-performance LEED instrument which operates with up to date digital power supply. The retraction mechanism has outstanding mechanical properties ensuring smooth day-to-day operation as experienced by our large user base over decades. The LEED 800 delivers exceptionally sharp and bright LEED patterns with high resolution in k-space (typical transfer width of 300 Å at 100 eV). The wide viewing angle (100° at 75mm sample distance) and minimal shadowing of the screen by the miniature electron gun give a maximum visible LEED pattern. For details, visit the LEED 800 Product Page.

FemtoLEED DLD L800

Nano-Scale Measurements of Surface Periodic Structures with Femto-Ampere Electron Probe

Collaboration with RoentDek in Germany.

The FemtoLEED with integral shutter enables nano-scale measurements of surface periodic structures with a femto-ampere electron probe. Instead of a fluorescent screen, it uses a delay line detector and allows for fully digital operation.

With its primary electron beam in the range of femto ampere, the FemtoLEED DLD L800 is specifically useful for investigations on sensitive organic samples. The fully digital system negates the need for an external CCD camera for live image capture. For details, visit the FemtoLEED DLD L800 Product Page.

Features

  • Primary electron beam in the range of femto ampere
  • Electron diffraction on insulating single crystal samples
  • Large coherence width
  • Powerful operation with digital LEED controller
