Tag Optics Inc.Computer-controlled varifocal lenses by Tag Optics Inc. offer Z-direction tunability and are available for several imaging modalities, including biological microscopy. The lenses utilize dynamic density gradients to create an aspheric lens with low aberration and near diffraction-limited performance with no moving parts. They can change focal length in submicroseconds, provide an increase in depth of field greater than 30× and are a simple add-on to any optical system.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 9/8/2022Zoom Microscope LensThe BS-1085 4K Apochromatic Monocular Zoom Microscope Lens from BestScope International Ltd. features an adopted apochromatic optical system.
