Low Temperature Microscopy

Low temperature piezo scanner

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-300K, and up to 16T magnetic field.

Low Temperature APO Objectives

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.

The continued reliance on liquid helium involves complex logistics, exorbitant costs, and uncertain supply. As a result, closed-cycle cryostats are rising in popularity across all fields that need measurements at low or fluctuating temperatures.

NanoMagnetics Instruments offers cryogen-free cryostats with unequaled and confirmed low mechanical vibrations, unheard-of low acoustic noise levels, and outstanding temperature stability with our cryogen-free cryostat. As a result, cryostats are particularly beneficial for scientific tasks like microscopy and optical spectroscopy as well as transport studies.

This cryogen free cryostat integrated variable temperature insert controls sample temperature from 1.3K to 300K. Simultaneous control of applied magnetic field up to 14 Tesla - all without the need for any liquid cryogens and using a single cryocooler.

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.
