Zur Info, scheint sehr hilfreich zu sein. Bernd _____ Von: Rossberg, Meaghan [mailto:MRossberg@hindsinstruments.com] Im Auftrag von Bryan, Amanda Gesendet: Dienstag, 13. Dezember 2005 22:10 An: beschoten@physik.rwth-aachen.de Betreff: Dear Herr Beschoten, A while back you visited the Hinds Instruments website and requested information on Magneto-Optical Kerr Effect measurements. I am writing to inform you of some new information that we have on our website describing MOKE measurements with photo-elastic modulators (PEMs) and to invite you to look at this information by clicking here: <http://www.hindsinstruments.com/PEM_Components/Applications/MAGNETO-OPTICAL KERREFFECT.ASPX> http://www.hindsinstruments.com/PEM_Components/Applications/MAGNETO-OPTICALK ERREFFECT.ASPX We also have a new application note that can be found here: <http://www.hindsinstruments.com/media/MOKE%20Application%20Note.pdf> http://www.hindsinstruments.com/media/MOKE%20Application%20Note.pdf PEMs are fixed frequency, resonance based polarization modulators. Because they operate at the resonance frequency of the optic, PEMs produce stable, pure modulation that, when incorporated into an instrument, can have a polarization sensitivity of 10-6. PEMs have several other unique features including: * A wide spectral range * No moving parts * A large acceptance angle * A large aperture Hinds Instruments is committed to properly supporting the researchers and scientists who use our products. We will do everything possible to insure your success when employing Hinds instrumentation. Please do not hesitate to contact us if we can help you with your polarization application.
