Molecular Vista “Vista 75” AFM-IR instrument
Combining AFM with IR (AFM-IR) spectroscopy
Vista 75 has been made more compact. With a completely new acoustic enclosure, Vista 75 now takes up over 60% less space than Vista One. Easy sample access and a one-handed AFM head clamp make tip and sample exchanges a breeze. The lightweight removable enclosure and open design make optical alignments easy.
Offering the highest resolution nanoscale chemical analysis instruments available.
- Sub-5 nm IR spatial resolution
- Unique chemical identification capability
Features
- Quick-change optics
- Pre-aligned optics make switching between PiFM + PiF-IR, s-SNOM, and Raman effortless
- Self-contained system
- No need for a special environment. Vista 75 is complete with built in vibration isolation, and a temperature controlled acoustic enclosure with dry air.
- Ultimate spectro-nanoscopy
- Photo-induced force microscopy (PiFM) and Photoinduced force infrared (PiF-IR) spectroscopy are the leading nano-IR techniques.
- 75 mm sample stage travel
- Sample size no longer matters. If it fits on the stage, Vista 75 can provide results.
- Exceptional AFM performance
- With an 80 µm (optional 100 µm) xy-scanner and a dual z feedback system, our AFM is top notch.
- Dynamic laser control
- The optical multiplexer handles alignments, polarisation, and normalisation automatically for effortless laser control.

APPLICATIONS
Semiconductor
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.
Polymer
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.
