nanoscopy - attocube

For many years, attocube systems has been pioneering cryogenic confocal microscopy. With the introduction of the
attoCFM series of confocal microscopes almost a decade ago, the optical investigation of single quantum devices on the
sub-micron scale at low temperature suddenly became available as a standard tool for scientists worldwide. Now once
again, the attoCFM-MC is redefining the state-of-the-art for low temperature confocal microscopy.
To improve the image quality in high resolution microscopy, confocal
microscopes are often used at cryogenic temperatures. At these conditions,
a combination of high resolution power, clear optical spectra,
and reduced thermal noise can be achieved.
Spectral lines become sharper as thermal broadening is typically
reduced at cryogenic temperature. Optical signals become stronger as
quantum efficiency improves because of reduced scattering and nonradiative
recombinations.

WIDE RANGE OF CRYOGENIC CONFOCAL MICROSCOPY APPLICATIONS
pioneers of precision
- carbon nanotubes
- Graphene
- high Tc superconductors
- semiconductor nanowires
For many optical microscopy applications cryogenic temperatures are
therefore inevitably required.
These advantages are beneficial particularly for high resolution optical
spectroscopy of semiconductor structures or single molecule detection.
Thus, investigation of the emitted optical energy of the sample due to
changes in the surrounding material, applied voltages, or the deposited
optical energy becomes feasible.

With its all-new optical head, the
attoCFM-MC opens the door to a whole
new plethora of application fields
through its easy-to-use and modular
design. Whether your are working at
the forefront of science in the fields of
photoluminescence / fluorescence of
e.g. semiconducting nanostructures
(quantum dots, nano wires, photonics
crystals, NV colour centers,…), Raman
spectroscopy (e.g. on graphene, carbon
CUSTOMER FEEDBACK
nanotubes, high-Tc superconductors)
or device fabrication for quantum
optics (such as deterministic in-situ
lithography on self-assembled quantum
dots to form strongly coupled cavities),
the attoCFM is the tool of choice to
accelerate your research and and to
achieve what matters most: creating
scientific impact.
Dr. Gervasi Herranz:
The installation of the attoCFM has been carried out in spring 2011 and the system has
been giving full satisfaction since its installation. We are very pleased with all the technical
information and assistance provided during as well as after the purchase. Since the
installation the system complies with all the specfications and requirements.
