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.

Best regards,

Amanda Bryan
