Lens
 

Lens can converge or diverge the transmission beam and form image of the object, Which is widely used in various applications.

Union Optic can provide all kinds of spherical and cylindrical lenses, usually we can offer:

Spherical: plano-convex, plano-concave, double-convex, double-concave, meniscus, dome lens, rod lens, ball lens, half ball
 

Cylindrical: plano-convex, plano-concave

Mixture: one side spherical, the other side cylindrical! We can offer!

Assembly: doublet, triplet, customer designed special lens kit
 

Usually lenses are not only used in visible band, but also in IR band and UV band, that means special material should be used. Now, Union Optic can offer lenses made of various materials such as CaF2, MgF2, Sapphire, Silicon, Germanium, ZnSe and etc. Union Optic can also provide various coatings for lenses upon your request.
