Meadowlark Optics, Inc. Eigenstate Generator Set EGR-λ

Meadowlark Optics Eigenstate Generator Set is a metrology tool that produces six polarization eigenstates: linear polarized light at 0, 90, +45, -45 degrees as well as circular right-handed and left-handed polarized light. These states are created by using a precision linear polarizer (black housing) and a precision quarter waveplate (blue housing) in conjunction with each other. The housings have an angular accuracy better than 1 arc minute and the pins on the housings mate to a v-groove and a flat groove in a quasi-kinematic fashion with magnets providing the holding force. This scheme facilitates precise, simple and fast indexing of the polarization eigenstates. Eigenstate Retarders are additional retarders that can be purchased at the same time as your Eigenstate Generator set and polarimeter. Wavelengths available from 450-1700 nm.okes Parameters 10 times per second to quantify the State of Polarization (SOP) and then graphically display the state on the Poincaré Sphere, Polarization Ellipse, or running chart. It contains no spinning waveplates, motors, or other moving parts to wear out or induce vibrations. Patented, proprietary algorithms provide high accuracy and calibration versatility. Two models offer polarization measurement over the wavelength ranges 450 nm to 1100 nm and 900 nm to 1700 nm.
