The PMI Polarimeter is a compact system with convenient computer control that accurately measures Stokes Parameters 10 times per second. It quantifies the State of Polarisation (SOP) and graphically displays the Poincaré Sphere, Polarisation Ellipse, or running chart.
Two wavelength ranges available
450 – 1100 (nm) Visible (PMI – VIS)
900 – 1700 (nm) Near Infrared (PMI – NIR)
The Meadowlark Optics system contains no spinning waveplates, motors, or other moving parts to wear or cause vibrations. Patented algorithms provide high accuracy and calibration versatility
Eigenstate Calibration Set (ECS)
The Eigenstate Calibration Sets are tools which produces six polarisation eigenstates: linear polarised light at angles of 0, 90, +45, -45 degrees as well as circular right-handed and circular left-handed polarised light.
These states are created by using a precision dichroic linear polariser in a black housing and a precision quarter waveplate in a blue housing. The housings are CNC machined so that the accuracy of the angles is better than 1 arc minute. Pins on the housings mate to a v-groove and a flat groove in a quasi-kinematic fashion, while magnets provide holding force. This scheme facilitates precise, simple and fast indexing of the polarisation eigenstates.
Large arrows on the housing indicate the transmission axis of the polariser and the fast axis of the waveplates for ease of use.
Available for wavelength ranges from 450-2000 nm.
