The photoelastic modulator provides unparalleled sensitivity in both polarization generation and polarization measurements. However, there are many non-PEM components in most polarization experiments that can adversely affect your results. The proper selection of detectors, demodulators, light sources and polarizers is crucial to obtaining the quality results that you need and that the PEM makes possible.

Hinds Instruments will apply our expertise in polarization measurements to help you select the correct components for your specific application and experiment. We will work with you to understand your experimental goals and help you achieve them by offering you a complete solution for your application that will include a photoelastic modulator and the surrounding instrumentation.

 

Rheology

Photoelastic Modulators can be used to determine the stress and viscosity of both static and flowing fluids. Photoelastic Modulation can detect nm scale changes in both sheer and viscous stress in DUV, visible, or IR spectrums.

Circular Dichroism

Photoelastic modulation is the established, de facto standard for research grade measurement of circular dichroism. Photoelastic Modulators offer a highly sensitive and efficient way of generating both left and right circularly polarized light. The correct selection of detectors, polarizers, PEM options, and demodulators are critical to monitoring the small levels of polarization absorption that can occur.

Magneto-Optical Kerr Effect (MOKE)

 Photoelastic Modulators offer a highly sensitive method for generating polarization states for Magneto-Optical Kerr Effect (MOKE) measurements in the DUV, visible, and IR spectrums. PEMs can also be used very effectively to analyze the polarization states of light after it has reflected off of the sample. The correct selection of detectors, polarizers, PEM options, and demodulators is critical to detecting the small levels of polarization change that can occur.

Fluorescence/Luminescence

Photoelastic Modulators provide an effective and sensitive method to generate different polarization states that can be used to excite fluorescence samples. PEMs can be used across the DUV, visible, and IR spectrums.

Ellipsometry

Photoelastic Modulators are frequently employed in ellipsometry applications and used in either the polarization state generation arm, the polarization state analyzing arm, or both, depending on the specific Mueller Matrix elements that need to be identified. An ellipsometer that uses two PEMs is capable of measuring all 16 Mueller Matrix elements, including the 4 anisotropic measurements. PEMs can be used at DUV, visible, and NIR wavelengths.
