Zero order Waveplates

Supplier
Cn-optics
Category
Waveplates
Origin
China

Zero order waveplates are constructed of two multiple order waveplates with their axes crossed. Thus the effect of the first plate is cancelled by the second, except for the residual difference between them. Zero order waveplates are much less susceptible to wavelength changes, can be up to 2% above or below the design wavelength with little effect on retardation. The waveplates should be considered for more critical application. Mounted Waveplates are available. (See Holder Size)

CeNing Optics co Ltd was found in 2004 in Fuzhou China, CeNing is committed to manufacturing high quality optics for customers all over the world. Started from a small workshop, CeNing has become a medium-size optics professional manufacturer. We employ approximately 35 staff, including six experienced engineers. Total company area is about 2000 square meters, We have built completely production lines from cutting, grinding, polishing to coating in house. In 2015 CeNing acquired a lenses factory in Suzhou, now CeNing is operating two locations. The plant is Fuzhou manufactures flat optics and coating, the plat in Suzhou manufactures spherical and cylindrical lenses. CeNing manufactures customized design optics from prototype to volume production. With thousands of existing tools and advanced techniques and equipments, our experienced engineers and workers have capability to produce challengling optics in short time. We always put quality-guaranteed in top priority, we employ a wide variety of metrology techniques and equipments like interferometers, high precision angular measurments, and lenses test systems. We implements ISO9001 for quality management and routinely test to applicable customers quality specifications.
