Request InfoHolo/Or Ltd.Holo/Or Ltd. has released multifocal diffractive optical elements for applications in microscopy and laser cutting. The optics allow a single collimated incident beam to focus simultaneously at several focal lengths along the propagation axis. The number of foci and the distance between them is predetermined during design. They can be manufactured on a window for a variety of working distances or as a hybrid element on a planoconvex lens.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueVital Sign Measurement PhotodiodeThe TOPLED® D5140, SFH 2202 photodiode from ams OSRAM provides high sensitivity for wearable devices and vital sign measurement.
