Request InfoApplied Scientific Instrumentation Inc.Applied Scientific Instrumentation Inc.’s CRIFF (continuous reflective-interface feedback focus) system reduces focus drift in high-power microscopy by monitoring the distance between the objective lens and the specimen’s coverslip. A near-IR laser-based optical detector senses minute changes in the distance and provides a feedback signal to the Z-drive focus controller. The system compensates for focus changes caused by temperature or mechanical variations, maintaining a specimen’s focus for hours with <100 nm of drift. The module fits on the camera port of most microscopes. It can be...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2023 IssueFLIM Camera SystemThe LIFA vTAU from Lambert Instruments is a camera-based system designed to transform fluorescence lifetime imaging microscopy (FLIM) for live cell applications.
