BioTek Instruments Inc.Microplate instrumentation manufacturer BioTek Instruments Inc. has added a patent-pending laser autofocus feature to its Cytation cell-imaging multimode readers. The autofocus design compiles all components into a single, user-installable cube that can be added to a new or existing system at any time, providing speed, reproducibility, and lowered risk of phototoxicity and photobleaching. The system enables the most appropriate autofocus method for the biology being studied. The readers combine multimode detection and microscopy with both image-based autofocus and a laser...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics May/Jun 2023 IssueTunable Laser SystemThe Tunable Laser System from Spectrolight Inc. is an all-in-one tunable light source system that enables precise selection of a broad spectral range from 410 to 1650 nm and easy bandwidth adjustment...Photonics.com 6/29/2023Compact UV LaserThe Spectra-Physics® Vanguard™ One™ UV125 from MKS Instruments Inc. is a compact UV laser designed for bio-instrumentation applications.
