Laser accessories and AFM options

FASTspectraTM OPO mid-IR laser
The new high pulse rate OPO laser extends the wavelength range of Resonance Enhanced AFM-IR to cover the 2700 to 3600cm-1 wavenumbers, extending capability to important spectroscopic regions and addressing wider range of applications, while still providing direct correlation to FTIR at the nanoscale.
The system sets new standards in resolution and sensitivity.
The new OPO laser also incorporates FASTspectra™ , a proprietary technology providing high speed IR spectra measurement in seconds improving time to data or enabling more detailed understanding of the sample. The FASTspectra -OPO laser compliments the standard FASTspectra QCL laser option that provides coverage from 950 to 1900cm-1

Nanoscale thermal analysis of a PS-PMMA blend deposited on glass. A scan (left) shows indents in the surface caused by temperature ramps (right). The data from the PS (red) and PMMA (green) clearly differentiate the two materials. Also shown is data from a thin film of PS on PMMA (blue) showing the initial penetration of the PS followed by the melting of the PMMA.

Environmental enclosure

Provides humidity control in an enclosed environment. The humidity control goes from 4% to 95%, non-condensing. Available on the nanoIR2, nanoIR2-S, and nanoIR2-FS.


Fluid imaging accessory:

Accessory for Fluid Imaging. Contact Anasys for upgrades to installed systems. Available on all Anasys systems.


Sample Heater/Cooler System:

Provides heating and cooling over a practical range of 4°C to 80°C. When used with a separate environmental enclosure, a working range of -20°C to 80°C is available. Available on the nanoIR2, nanoIR2-S, and nanoIR2-FS.
