Polarimeter (PMI)

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.

What's New?

We’ve recently refreshed our website, and we hope that you will find the changes to be a big improvement. We’ve worked hard to make it easier to navigate the site, and to find exactly what you need from among our vast and diverse range of products.

Missing e-commerce?

One thing that we’ve not carried over from the previous site at this time is the facility to order online for a select range of our products, which you may have been used to in the past. “Off-the-shelf” items represent a small part of our product range; most often a purchase requires a more in-depth discussion between our sales team and the customer to match the right product to the user’s application. For this reason we have focussed on making it as easy as possible to request a quotation from our sales team.

Please rest assured that we will get back to you with pricing promptly, and will work with you to make sure the products you buy are exactly what you need. Once you’re ready to order, our sales team will work through the process with you, to make it as seamless as possible.

Once you’ve selected all the items you’re interested in, by clicking “Add to Quote” on the product page, just click “View Quote Request List” or the icon in the top navigation bar, check your list, set quantities, complete your details and submit the form. Our sales team will respond by email, in a timely manner.

If you have any other questions in the meantime, please get in touch directly.
