Request InfoTofra Inc.Tofra Inc. has introduced a focus drive with an integrated controller for optical microscopes. It provides computer-controlled movement of fine focus and retains manual movement of coarse focus. Mounting adapters are available for all major microscope brands. The focus drive operates in the entire vertical range of the microscope with up to 1-nm resolution. It connects directly to the computer serial port (or to the USB port via a USB-to-serial converter) with a custom cable and can be used with desktop or laptop computers. It can be daisy-chained with stage and filter wheels to create an...See full productRelated content from Photonics MediaPRODUCTSPromoted Content November 2022 IssueRapid Automated Modular MicroscopeRapid Automated Modular Microscope is mounted on the RAMM frame that supports the microscope assembly and the stage in a manner that ensures close coupling between sample and objective to minimize...Photonics.com 3/21/2024Probe MicroscopeThe INX™ 760 from VIAVI is a single, duplex, and multi-fiber probe microscope for reducing time in the construction, activation, and maintenance of complex fiber networks.
