ZYGO 

Juka Optics insists on controlling the precision of the lens quantitatively with various professional testing machines. We have two sets of ZYGO Interferometers and one set of VECCO Interferometer.They can detect the surface shape of lenses with a diameter range of 5-200mm.

VECCO

The interferometers are equipped with a variety of standard lens,such as F0.5,F1.5,F3.3,F7.6,F11. They can detect the surface shape and curvature radius of ± 0 ~ 1000mm.

With the transmission and reflection center instruments, the center deviation of the lens can be effectively detected. The reflective centration accuracy test instrument can detect the eccentricity of each curvature of the lens group, and can also measure the focal length.

Reflective Centration Accuracy Test Instrument

The Shimadzu spectrophotometer can detect the reflectance of the coated test piece and effectively reflect the coating condition.With the transmission and reflection center instruments, the center deviation of the lens can be effectively detected. The reflective centration accuracy test instrument can detect the eccentricity of each curvature of the lens group, and can also measure the focal length.

Our surface finish inspection is strictly in accordance with ISO10110-1 standards, and each lens is individually inspected.
