Description

The invention and subsequent development of scanning probe microscopy (SPM) methods have produced the necessary tools for a step forward in optical measurements.

The possibility to go beyond the Abbe diffraction limit has been achieved with the Near-field light optical microscopes (SNOM). They employ SPMs precision of piezoelectric raster-scanning together with sharp probes to obtain light optical images at subwavelength resolution.

Particular care has been taken to different applications from solid state to biomedicine.

The goal of our company is to give to the customers the instrument that best fit their needs.

This product is the result of a collaboration between A.P.E. Research and National Research centers.

SNOM head		SPMCU2-PI
SNOM Head is suitable for Simultaneous Acquisition of Optical signal (up to 3: reflection, transmission and collection mode) and Topographic signal. Optical signals acquisition by 2 Photomultipliers. Sample holder size: 30x30 mm; Translator range 13 x 13 x 13 mm; servo assisted z movement. 2 Optical Vision System integrated into the SNOM head: one optical vision system to monitor probe approaching on the sample and one Inverted optical microscope for Transparent sample. A.P.E. Research A.P.E. Research suggests LovaLite SNOM probes. Probe Holder is suitable for any Commercial SNOM fibers.		SPM control unit SPM Control Unit and PC (equipped with a multi input-output board) drives the scanner, data acquisition and sample motion. Tip to sample distance is controlled by ultra-low noise analog feedback, digitally driven by PC.
Dual Demodulator		HVA3-PI
A.P.E. Research Dual demodulator for Optical signals acquisition.		High Voltage Amplifier HVA is an amplifier module projected to drive TriA-SNOM Heads.
Ordinateur, carte et logiciel d'acquisition
Software runs under Windows and is composed of a multi-window applications for instrument control and data acquisition. The software comes equipped with simple filters for immediate analysis of acquired images. The software controls all the parameters of the instrument. A.P.E. Research instruments are equiped with the "open source" SPM data analyze software Gwyddion (available on Windows and Linux). The software SPIP is also available on request.
