As the large concave lens factory in China,JUKA Optical has mastered mature mass production process, and max diameter can reach 500mm. the large plano convex lens and concave lens are usually used to machine vision, astronomy telescopes, semiconductor, projectors, enlargers, spotlightsand other projection and illumination applications.

Main products of JUKA Optics are optical lens, optical prisms, and optical window with almost all optical glass and crystalline materials.We provide the whole solutions for our customers from design to the final products. 50% of our optical products are exported to foreign countries, including Europe, North-America, Russia, and parts of countries in Asia. Sichuan JUKA cooperates with many institutes and colleges for their scientific research and OEM is also available.

Juka Optics has a complete processing production line for optical components.It mainly include cutting, rough grinding, milling, fine grinding, edging, polishing, coating, cementing, painting, assembly.  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.

Plano concave lens has a negative focal length and is typically used to cause a collimated beam to diverge as in a Galilean type beam expander or telescope. Because the spherical aberration of the Plano-Concave is negative, it can be used to balance the aberration of other lenses. this PCV lens is widely use in optical display systems, projection optics systems, imaging and laser measurement systems.
