Twisted Nematic Liquid Crystal Devices

Summary Meadowlark Optics has been a leader in nematic liquid crystal (LC) devices for over 25 years, pioneering liquid crystal variable retarders (LCVRs) for precision optical applications. LCVRs offer low-voltage electrical control of retardance (typically ≤20V) and have largely replaced high-voltage Pockels cells in many applications. However, Twisted Nematic (TN) Liquid Crystal Devices provide distinct […]

Liquid Crystal in Precision Optical Devices

Summary While liquid crystal technology is widely known for display applications, its role in scientific and engineering fields is rapidly expanding. Liquid crystal devices (LCDs) are now critical for beam steering, wavefront modulation, and polarization switching in precision optical systems. Unlike traditional flat-panel displays, high-performance liquid crystal optics require specialized construction techniques to achieve superior […]
