Alpha300A – AFM Microscope

The Witec Alpha 300A - AFM microscope was developed and designed to allow combination with other image acquisition techniques such as confocal Raman imaging. All of these image acquisition techniques are integrated into a compact microscope system structure and maximize footprint. Users, through easy operations such as rotating the control axis, can adjust back and forth between different methods of use. Modules can be easily combined with the AFM such as luminescence, fluorescence, polarization analyzer, bright field, dark field, SNOM and Raman image acquisition units.

  • Research grade optical microscope with 6 x objective turret
  • Video system: color video camera
  • LED white-light source for Köhler illumination of tip and sample
  • Manual sample or motorized positioning in x- and y-direction
  • Various piezo-driven scan stages, fully capacitive feedback-controlled
  • Microscope base with active vibration isolation system

WITec alpha300 is an operational and modular product line

Allows you to easily upgrade and expand the system while achieving optimal costs.

This is a product line that combines almost all scanning probes and optical microscopes to serve and meet many other customer requirements.

Each WITec alpha300 product line is equipped with new functions in the form of additional integrated features or can be upgraded later.

Hardware and software are used on all features or at the same time to ensure the best possible compatibility and ease of use
