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.

Dielectric Loss Tangent Testing Instruments
-
Insulation materials in electrical equipment are used between a pair of electrodes; therefore it can be expressed as capacitors. Applying AC voltage to a capacitor with insulation materials causes an energy loss due to the leak current, the dielectric polarization, and the partial discharge. Because of this, the phase of the capacitor current is more delayed than that of a zero-loss current (reactive current) flowing in an ideal insulation material. The delay angle is called "Dielectric Loss Angle", and the tangent is "Dielectric Loss Tangent" (tanδ). Please refer to the technical guide explained in detail.

Multi-angle Polarized Light Scattering Measurements
LISST-VSF
-
The LISST-VSF covers the angular range from 0.094 to 150°. Of this, the range 0.094 to 14.9° is covered with Sequoia’s 32-ring detector optics as in the LISST-200X. From 15 to 150° scattering from the length of a laser is viewed by a rotating eyeball. These data produce P12 and a noisy estimate of P22 (no P22 estimate at 45 and 135°).

PXI Solid State Multiplexer Module, Single 6-Channel, 30 A
40-667C-012
Multiplexer Module
The 40-667C-012 is a single 6-channel 30A MUX and is part of our range of high current multiplexers occupying two slots of PXI chassis. Each multiplexer switch uses a fully isolated solid state relay which has been designed to offer fast operation under hot switching conditions and high inrush current with no operational life degradation. Each multiplexer channel can support 10A of continuous current and switch up to 200V signals. The switches can sustain inrush currents in excess of 50A. AC or DC signals can be switched since the switch is polarity insensitive.

Welcome to Thorlabs; below you will find links to optical components and systems, a subset of our entire line of photonics products. All single element optical components can be found under the optical elements link with the exception of optical components that have polarization properties since they have a separate link. Multi-element systems like beam expanders and objective lenses as well as interferometers, fiber collimators, reference cells, modulators, and other optical devices can be found by choosing the optical systems link. Thorlabs also manufactures an extensive line of free-space and fiber optic isolators; stock items ship the same day that they are ordered while our custom orders benefit from our streamlined design and manufacturing process, which minimizes lead time.
