DRUM LENS/FLYEYE LENS

Support from a design consistent with the working distance.

● Drum lenses are widely used in semiconductor manufacturing and industrial inspection devices that require a high degree of accuracy.

● This type of lens can be also used for high-accuracy integrated micro cylindrical lens arrays.

● This type of lens can be manufactured by using CaF2, which is ideally suited for application in lasers.

Application: Beam homogenizers and semiconductor manufacturing devices (steppers)
