The FVM400 uses fluxgate technology to measure the three vector components of the magnetic field. The fluxgate sensors are packaged in a 1" square by 4" long probe that is connected to the handheld electronics unit by a modular telephone cord. The sensor can be located up to 100 feet from the electronics unit.

Standard OptiMag systems (OM series) feature magnetic fields of 6 to 9 T, sample tube diameters of 1.25 in to 1.75 in, a 12 L useful capacity helium reservoir, and bottom optical access along the vertical field axis.

Designed to operate with the Lake Shore model ST-500 high stability microscopy cryostat, this system allows microscopy measurements to be performed in fields of 7 T. (Contact us if you require a system with higher fields.) The system comes with X-Y-Z translation stages for sample scanning and focusing, and is designed for magneto-optical imaging at helium temperatures.

Separate variable temperature cryostats are supplied that fit into the magnet bore for operation between 1.5 K and 325 K (800 K optional). Magnetic fields up to 9 T (niobium-titanium) or up to 14 T (niobium-tin) upon special demand. A special compact system is also available for use in microscopy experiments. The system allows entry of the cryostat through the bottom of the room temperature bore with viewing through the top of the bore.

These Lake Shore closed-cycle refrigerator cryostats cool the sample in exchange gas. Helium circulates through an independent cooling loop to cool samples to temperatures as low as 1.5 K, allowing nearly unlimited operation. The sample space is separate from the cooling loop, minimizing the risk of blockages. With a wide range of electrical feedthrough and window options, they are a versatile choice for making cryogenic measurements without using liquid helium.

Lake Shore offers cryogenic cold traps (CCTs) that use mechanical coolers. These traps are primarily used in the adsorption of noble gases, including helium, neon, argon, krypton, and xenon. CCTs aid in the extraction of such gases from geological materials collected from volcanic hot springs to get insight into the planetary evolution of the Earth. They are also used to adsorb various oxygen isotopes from meteorites and polar ice caps, and ocean island olivines.

Optimized for Mössbauer spectroscopy, the Lake Shore CCS-800 provides uniform cooling of powders and irregularly shaped solid samples without introducing vibrations (and subsequent line broadening). Samples are top‑loaded into static helium thermal exchange gas, eliminating the need for careful thermal anchoring. The CCS-800 is supplied with an integrated pneumatically isolated mounting stand.
