Low Temperature Microscopy

CLOSED-CYCLE BOTTOM LOADING CRYOSTAT is a configurable NanoMagnetics Instruments platform for low-temperature optical, magnetic, electrical, spectroscopy, and microscopy experiments using the access, sample space, and field options supported by the selected cryostat.

LT-SCM works by passing a laser beam through a light source aperture which is focused by an objective lens into a small area on the surface of the sample and an image is built up pixel-by-pixel by collecting the emitted photons from sample surface.

The LT-AFM/MFM is an alignment-free Atomic Force Microscopy system equipped with a Fibre Interferometer operating at 1310 nm, 15 fm/√Hz noise level with an operation range of 20mK-300 K, and up to 16 T magnetic field.

With the help of a micron-sized semiconductor Hall sensor probe, our LT-SHPM enables user to map the surface Hall voltage V H as a function of position, which directly gives the spatial distribution of the local magnetic induction.

LT-sSNOM has the capability of near-field imaging and spectroscopy together with other AFM modes such as contact, dynamic, MFM, cAFM, KPFM, PRFM. The tip-sample interface is illuminated by off axis parabolic mirror and scattered light is detected by heterodyne interferometer.

Low Temperature APO Objectives

Break free from the logistical challenges and rising costs of liquid helium. NanoMagnetics Instruments designs and manufactures a established portfolio of cryogen-free cryostats, also known as closed-cycle cryostats. Our systems are engineered to provide an ultra-low vibration environment, making them the ideal solution for the most sensitive microscopy, spectroscopy, and transport measurements.

Experience outstanding temperature stability, exceptionally low acoustic noise, and the freedom of a completely cryogen-free laboratory.

LT-SNVCM uses a single NV Centre to image magnetic domains. The NV Centre is excited with a green laser through Low Temperature Apochromatic Objective with 0.82NA & 0.95 mm WD. Single photons emitted by the NV centre are filtered and counted by an APD to obtain ODMR spectra with an RF antenna. Magnetic image is built up pixel-by-pixel by counting the number of emitted photons from the NV centre.
