PanScan Lumin-SLT

The new PanScan Lumin-SLT combines Cryo-STM/AFM with integrated optics that offers industry-leading light collection efficiency. The combination of high-efficiency optics and high-stability SPM of the Lumin-SLT enables the study of the interplay between morphological, optical and electronic properties of a wide range of materials.




Ideal for:

  • Cathodoluminescence (CL)
  • Photoluminescence (PL)
  • STM light emission (STM-LE)
  • Raman spectroscopy





  • Up to 70% light collection efficiency
  • Optical wavelengths from deep UV to far IR
  • Integrated parabolic mirror with in-situ 3D nanopositioners
  • Atomic resolution

PanScan Tesla SPM with Magnetic Field

The Tesla model offers closed-loop cooling for stable low-temperature SPM measurements inside and outside the magnet, ultra-low drift, exceptional spectroscopy functionality, and an integrated cryogen-free superconducting magnet in a surprisingly compact, simple, and affordable package.


  • Integrated cryogen-free magnet
  • No coolant consumption
  • Atomic resolution from 9 K to 400 K
  • Superconducting Magnet (3 – 6 T)
  • Conventional electromagnet options available
  • Allows SPM operation inside and outside the magnet
  • Extremely low drift
