Buyer’s Guide

Scanning probe microscopy

Sponsored by Bruker Nano Surfaces

Bruker’s Inspire™ delivers, for the first time, highest-resolution nanoscale chemical and property mapping combined with radical productivity advances and uncompromised AFM performance. The integrated, self-optimizing system acquires nanoscale infrared absorption and reflection maps at regular AFM imaging speeds, without the limitations of indirect mechanical approaches or added complexity for the user.
