Liquid Crystal Devices

The effective birefringence of liquid crystals can be changed by varying an applied voltage.

Liquid Crystal Variable Retarders are solid state, real-time, continuously tunable waveplates.  Liquid crystals are birefringent materials whose effective birefringence can be changed by varying an applied voltage.

Meadowlark Optics Liquid Crystal Retarders are constructed using precision polished, optically flat fused silica windows spaced a few microns apart.

A Liquid Crystal Variable Retarder is the fundamental component used in the following devices and systems.

• Variable Attenuators and Rotators
• Variable Beamsplitters
• Spatial Light Modulators
• Non-Mechanical Shutters
• Beam Steerers
• Optical Compensators
• Polarimeters
• Tunable Filter

Description
Our standard Liquid Crystal Variable Retarders (LVR) provide a minimum retardance range of ~30 nm to at least half-wave at the specified wavelength. With specific UV devices from 350-450nm and MWIR from 3.6 to 5.7 microns

Our Liquid Crystal Polarization Rotator continuously rotates the polarization direction of a monochromatic, linearly polarized input beam. With three types of rotators based on parallel aligned nematic, twisted nematic and ferroelectric liquid crystals each providing different features in terms of contrast, speed, achromacity

The Variable Attenuator (LVA) offers real‐time, continuous control of light intensity. Our attenuator consists of an LC Variable Retarder (with attached compensator) operating between crossed linear polarisers. With crossed polarisers, light transmission is maximized by applying the correct voltage to achieve half‐wave retardance from the LC cell

Founded in 1979 by Tom Baur a pioneer in the field, awarded the SPIE G.G.Stokes award in 2018, Meadowlark optics are polarisation experts, providing polarisation components, liquid-crystal devices, spatial light modulators and polarisation instrumentation.

In the twenty-first century, Meadowlark products help position customers worldwide to pioneer their own innovations. These include advances in liquid crystals with one-of-a-kind polarization controllers and the Liquid Crystal Stokes Polarimeter. In other areas, they measure there waveplate product line to subnanometer precision. One thousandth of a wave of retardance is our standard accuracy.

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.
