The LVT-100 from Meadowlark Optics is an OEM liquid crystal variable retarder that operates from 450 to1800 nm. It has a retardance range of -30 nm to λ/2 and beam deviation of 3 arc min. This waveplate has a clear aperture of 12.5 mm with a diameter of 25.4 mm and a thickness of 6.35 mm. The waveplate has a surface quality of 80 – 50 scratch dig and is ideal for space constrained or OEM applications. For even tighter mechanical constraints, unmounted cells are also available with flying leads or custom connectors.
