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 2/8/2024Fluorescence Imaging LensesThe Melles Griot XPLAN™ CCG Lens Series from IDEX Health & Science are fluorescence microscope imaging lenses for life science and medical applications.
