A still from a video (link below) shows polymer microdisks being transferred to glass via laser catapulting. Laser catapulting can also be used to fabricate an array of microlenses directly on top of a photodetector array (inset), useful for directing more light onto the most sensitive parts of the detector.

Laser catapulting is fast, low-cost way to create microlens arrays

Single laser pulses drive polymer microdisks from a film onto the target; further pulses shape the disks into microlenses.
