Optical Bk7 Spherical Lens for Laser Module

Basic information:
Typical material : BK7, Fused SilicaMass production leading time: 4-5weeksFactory: ISO9001 Samples: Free samples offeredSevice: OEM & ODMPackage: As requestexperience: 18 yearsSpecification: As requestPort: Fuzhou Port Original: ChinaQuartz productsis 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
