Request InfoNavitar Inc.NanoVue, a 248-nm 4× deep-UV zoom lens manufactured by Navitar Inc., works with infinity-corrected microscope objectives to enable optical inspection with <0.1-μm resolution and a zoom range of 0.75× to 3×. When using the 100× objective corrected at a 200-mm tube length, the range can be extended to 75× through 300×. Using a 100× infinity-corrected deep-UV objective with a 2/3-in. sensor results in a field of view from 0.14 to 0.37 mm. Applications include deep-UV reticle and photomask inspection, thin-film measurement, wafer inspection, failure analysis and process control.See full productRelated content from Photonics MediaPRODUCTSPromoted Content November 2022 IssueLS850 Fully Automated MicroscopeThe powerful, new LS850 Microscope is the latest generation of our fully automated three-channel flagship model and offers the latest advances in optics, cameras, throughput, and user flexibility....Promoted Content March 2024 IssueUltra-Precision Microscopy DemoThe Nucleus™ microscopy platform provides a complete set of interchangeable hardware modules and software tools, making it ideal for OEMs and lab managers engaged in fluorescence cellular...Promoted Content April 2024 IssueGet More Data: Automate Your MicroscopeZaber offers a selection of standard and customized motorized microscope stage products.
