Molecular Vista “Vista 200” PiF microscope
For nano‑IR chemical analysis.
With a 200 mm × 200 mm sample stage Vista 200 is perfect for analysing wafers or photo masks. Vista 200 can be configured with either a vacuum chuck with magnets or a specialised EUV mask holder. This instrument is perfect for 4-, 6-, or 8-in wafers. PiFM operates in true non-contact mode. The instrument doesn’t touch your pristine samples, so they stay clean – and so does the tip.
Offering the highest resolution nanoscale chemical analysis instruments available.
- Sub-5 nm IR spatial resolution
- Unique chemical identification capability
Features
Built for industry
-
Maximise efficiency, minimise disruption
- The 300 mm wide sample access door minimises thermal disturbances that cause drift while allowing you to maximise throughput. With Molecular Vista’s forward moving stage and user friendly head mount, both the tip and sample can be easily swapped without opening the entire enclosure.
-
Self-contained system
- No need for a special environment. Vista 200 is complete with built in vibration isolation, a temperature controlled acoustic enclosure with 0.1 ºC precision, and a fully enclosed beam path with dry air.
-
Streamlined processes
- Vista’s included data analysis software allows your team to go from measurements to presentation-ready results quickly. Tight integration with this data acquisition software allows you to get the answers you need in real time. The scripting API allows custom recipes, and files are open so integration with 3rd party software is easy.
-
Exceptional AFM performance
- With a 120 µm xy-scanner, 12 µm sample z-scanner, and integrated vibration isolation, the AFM is top notch. The high-bandwidth dual-z feedback system allows true non-contact AFM for IR PiFM.

APPLICATIONS
Single-molecule level sensitivity
PiF-IR PiF-IR spectra (magenta and green) show the chemical differences on and off these peptoid nano-sheet fragments. PiFM PiFM chemical maps are able to detect peptoid fragments that are only 0.5 nm taller than the surrounding material! Scan dimensions: 500 nm × 500 nm × 1.7 nm.
Sub-5 nm IR spatial resolution
PiFM chemical mapping provides unbeatable lateral IR resolution for analysing surface chemistry. An elementary cellulose fibril is embedded in the lignin matrix of a cell wall from spruce wood. Scan dimensions: 150 nm × 150 nm × 10.5 nm.
