  • SQUID Magnetometer

    S700X - Cryogenic Ltd.

    The S700X SQUID Magnetometer is the most sensitive instrument for DC and AC measurement of magnetic properties as a function of magnetic field and temperature. Numerous different experiments may be performed with this unique instrument. The SQUID sensor at the heart of the system has an input noise power sensitivity of approximately 10-30 Joules per root Hz. This energy sensitivity is 108 better than any semiconductor device and accounts for the instrument's ability to resolve extremely small magnetic signals with accuracy and speed. The S700X has several modes of operation. The most widely used is the measurement of total magnetic moment made by moving the sample through a set of pick-up coils. During the measurement the sample temperature and applied magnetic field are precisely controlled. The second order gradiometer configuration used for the pick-up coils is insensitive to the externally applied field but allows samples of 10-11 Am2 total moment to be resolved with ease.

  • Fourier Transform Optical Spectrum Analyzer, 600 - 1700 nm

    OSA202C - Thorlabs, Inc.

    Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.
