Product Description
Basic information:
Quartz products is demonstrated using two planar substrates and homogeneous liquid crystal (LC) layer
Top substrate has slit electrodes on its outer surface and the bottom has a transparent electrode
on its inner surface
An applied voltage across the cell induces cylindrical-like gradient refractive index
within the LC layer which causes light to focus focal length is tunable by the applied voltage
Such a cylindrical lens can be easily fabricated with wide aperture size
Application:
----WSS
----Telecommunication System
----Laser Measurement System
----Scan System
