Analytical Instruments
Holmarc has introduced a new innovative high sensitivity and high magnetic field Spectroscopic Faraday/Kerr effect measuring equipment utilizing the VIS-NIR wavelengths. HOLMARC A216 FR/KR test station provides standardized testing solution to fit wide ranging optical rotation measurement applications. The modular hardware design allows user to take automatic measurements of Faraday effect, MOKE & Ellipsometry in a single instrument.
Designed for magneto optic material research and testing including magnetic characterizations of ferromagnetic and ferrimagnetic films and materials. Measurement include magnetic hysteresis loops of ultra thin magnetic films and multilayers, Ellipticity measurements, Thin film thickness measurement of dielectric materials, Refractive index, Delta and psi measurements etc. System can be operated in Polar, Longitudinal and Transverse configurations.
