FEI Life Sciences (acquired by Thermo Fisher)The Tecnai Femto ultrafast electron microscope from FEI Co. captures ultrafast events and processes measured in femtoseconds, including the absorption of light energy and its transformation into heat, or mechanical changes and the crystallization or recrystallization of materials. Ultrashort laser pulses stimulate a brief flash of photoelectrons from the electron source, and a pulse of laser energy directed at the sample acts as a stimulus. The device achieves high temporal resolution operating in stroboscopic mode by combining images of the sample at a given delay between stimulus and...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jan/Feb 2024 IssueLaser Scanning MicroscopesEvident’s FLUOVIEW™ FV4000 confocal laser scanning microscope and FV4000MPE multiphoton laser scanning microscope, feature advancements in imaging technology that empower researchers to...BioPhotonics Jul/Aug 2022 IssuePhoton-Counting Sensor and CameraGigajot Technology Inc.’s QIS41 camera, built around the GJ04122 sensor, pairs well with standard 4/3-in. microscopy optics, bringing high resolution and low-light performance to scientific and...BioPhotonics Sep/Oct 2023 IssueUpright MicroscopeThe ECLIPSE Ui integrated microscope-based viewing system from Nikon Instruments Inc. is designed for clinical and pathological observation.
