Our lens array is made by mold pressing.
Traditionally, lens arrays were made by bonding cell parts one by one, but it is now possible to make them together as a plate using a mold.
Pressed by mold can provide cost merit over laminated products, while makes mass production possible.
Lens cells can be not only spherical surfaces, but also of variety of shapes such as aspherical, cylindrical, irregular, eccentric, etc.
Micro lens arrays with tiny cells and double-side lens with two different shape of surface can also be produced.
We also have standard products which do not need mold offered by customer. Pleaes consult us for details.
Application
Semiconductor equipment, visual inspection equipment, FA equipment, projectors, 3D printers, etc.
