Double-sided microlens arrays (DSMLAs) play a crucial role in improving the performance of optical devices, supporting applications from advanced imaging systems to laser beam homogenization. However, ...

A new laser-based alignment tool reportedly is the first of its kind to work effectively with twin-barrel extrusion systems. Initially, the application was almost a happy accident, according to Hamar ...

[Left] Semiconductor layers are stacked using concentric metalenses as alignment marks. [Right] Light shines through these marks to project a hologram. The alignment or misalignment of the lenses ...

Researchers at the University of Massachusetts Amherst have invented a new way to align 3D semiconductor chips by shining a laser through concentric metalenses patterned on the chips to produce a ...
