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, ...

To develop novel confocal fibre-optic laser method (CFOLM) for accurate and objective measuring of the dioptric power of both positive and negative intraocular lenses (IOLs). The CFOLM principle of ...

Optically opaque materials present a series of challenges for alignment and overlay in the semi-damascene process flow or after the processing of the magnetic tunnel junction (MTJ) of a Magnetic ...

[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 ...
