Low temperature strong magnetic field confocal microscope without liquid helium attoCFM

Low temperature strong magnetic field confocal microscope without liquid helium attoCFM
After years of development, the low-temperature strong magnetic field confocal microscope attoCFM system produced by Germany's attocube company has become the standard equipment for studying the optical properties of quantum dots and quantum devices at the nanoscale.
To improve image quality, confocal microscopy needs to work in a low-temperature environment to achieve the goal of improving image resolution, clear optical spectra, sharpening spectral lines, and reducing noise. Meanwhile, the reduction of scattering and non radiative effects at low temperatures, as well as the improvement of quantum efficiency, contribute to the enhancement of optical signal intensity, making it possible to study the relationship between emission energy and other factors.
The attoCFM is equipped with a brand new attoDRY series liquid helium free thermostat and magnetic field, as well as a new scanning head attoCFM-MC. It is simple and easy to use, and its modular design meets the requirements of openness and flexibility in optical experiments. Due to its ability to provide a wide range of experimental parameters such as temperature, magnetic field, electric field, optics, and sample position, atoCFM has a wide range of applications in the field of scientific experiments. The types of samples that can be measured include quantum dots, one-dimensional nanowires, graphene, two-dimensional crystal materials, and various other materials. The application fields cover quantum, two-dimensional material magnetism, optical photoluminescence spectroscopy, electroluminescence spectroscopy, Raman spectroscopy, photocurrent, and research on electrical transport properties, among others.
