Optical Cryostats for Microscopy

Andors Microstat range of optical cryostats provide cryogenic sample environments with a variety of design and performance characteristics. Available as liquid Nitrogen and liquid Helium flow cryostats with sample-in-vacuum environment and sample temperatures from <2.2K to 500K. The Microstat range offers some of the most efficient and cost-effective cryostats for Optical Microscopy. They are equally suited to work in any orientation on an optical bench or integrated into a commercially available microscope. We also offer a range of optical cryostats for spectroscopy.

Cryostats Applications for Microscopy

Ultraviolet-Visible Spectroscopy

Ultraviolet–visible spectroscopy or UV/Vis refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region.

Microstat systems are available with a wide range of window materials, including Spectrosil B/WF for UV/vis wavelengths.

Contact Our Application Specialists

Magneto-Optical Kerr Effect

Magneto-Optical Kerr Effect (MOKE) can be used to investigate the magnetization structure of materials.

Using the Microstat He coupled with a narrow rectangular tail-set, samples can be inserted between the poles of an electromagnet while maintaining optical access to the sample.

Micro-Raman

Raman Scattering or the Raman effect is the inelastic scattering of a photon by molecules which are excited to higher vibrational or rotational energy levels.

The Microstat range of cryostats allows for Raman spectro to be recorded using microscopy objectives in a temperature-controlled sample-in-vacuum environment. Windows, both top and bottom, allow for reflective and transmission measurements.

Micro-photoluminescence

Micro-photoluminescence or Micro-PL spectroscopy is a powerful tool for investigating the optical and electronic properties of single nanostructures.

The Microstat range of cryostats allows for mapping of semiconductor microstructures with sub-micron spatial resolution and single photon counting across a wide range of temperatures.

Micro-FTIR

FTIR spectroscopy, widely used for polymer research, inorganic chemistry, pharmaceutical or drug related research, as well as solid state and semiconductor physics.

The integration of the Microstat range of cryostats can allow for spectral mapping of samples across a wide range of temperatures, giving localized information about your samples. Window flanges are available to span the near to extreme IR.

Contact Our Application Specialists

Fluorescence Spectroscopy

Fluorescence spectroscopy, a type of electromagentic spectroscopy that analyses fluorescence from a sample, and can be applied to microscopy samples using the Microstat range of cryostats.

Cryostats using liquid nitrogen or liquid helium offer temperature to below 4 K with minimal distance between sample and objective.
