CPG optics starts is own Cylindrical lens fabrication from year 2003. With now over 10 year’s experiences, she served a lot of customer from different industries. Like lighting, image sciences, aerospace, laser etc.
CPG also can design the cylinders according to the request. In CPG, we developed several different testing methods to secure the qualities. With our engineers know-how mind, we are surely can provide the products with sable qualities.
Dia0.5mm to Dia500mm (include the stripe joint shape)
Optical glass/color glass/fused silica/Ge/Silicon/ZnSe etc.
Flatness: 1/4 Lambda
S/D: 20/10(or better)
Fabricating process technics introduction:
As we all know, during the polishing stage of the optical components fabricating, we need to make the contact surface rotating, then we could get a precision surfaces after this kind of step. It is all ok with the symmetry spheres, windows etc. because the trace of the polishing is uniform, and it is more easy to get a smooth surface with the error with 50nm. But for the cylindrical lens fabricating, the polishing machine was designed to do the polishing in two directions, and in fact the gridding between the surfaces is not uniform, then we can see the stripes on the surface. Some of them are small, even hard to find in our naked eye. But in the high resolution application, the defect will show out.
