Liquid-Crystal Controllers

Optical Finesse offers two standard lines of liquid-crystal controllers, all suitable for driving continuously-variable LC devices such as variable retarders, polarization rotators and switches, shutters, variable attenuators, tunable color filters, and polarization-state generators/analyzers.

Our LCC series controllers are manually-controlled devices ideal for prototyping, laboratory, and manufacturing applications. Our µ-micro series LC controllers are digitally-controlled devices capable of driving two or four channels and operating with or without a host computer.

All our controllers are manufactured in Colorado using a rigorous seven-step quality control process, and are backed by our 12-month warranty. All products are 100% RoHS compliant.

Compact, rugged, and economical, our controllers have been field-proven in world-class installations and production lines around the globe. Optical Finesse specializes in OEM designs for stereoscopic display, manufacturing, and projection applications. We welcome the opportunity to tailor our standard controllers to meet your unique set of needs.

Note that our LCC-230 two-channel 30V USB LC controller is available exclusively from LC-Tec. Please contact us directly for OEM specials of this design.


This two-channel controller is our most economical product-line offering, perfect for driving nematic cells, as either a hand-held or benchtop accessory.
