ThunderScan provides ultra fast Z-stacking capabilities for microscopy applications by remotely scanning image planes thanks to an integrated tunable lens.

Z-scanning is achieved without moving sample stage or objective thus allowing vibration free and fast acquisition time only limited by camera performance.

As aberration free and diffraction limited optical device, the ThunderScan Z-scanner provides precise and repeatable Z-steps.

ThunderScan fits in between video port and camera. ThunderScan is compatible with all kind of microscopes: upright / inverted, BF, FL, SPIM, 2Photons, etc. and requires no microscope modification or additional accessories. All types of objectives magnification / NA can be used,including high numerical aperture and dipping lenses.

Sucessfully used for applications such as: High-speed volumetric imaging of weak fluorescent specimens – Electrophysiology, calcium imaging – Fast 3D recording of dynamic events or moving specimens – Live Imaging of cellular dynamics, 3D neuronal activity – Extended depth of focus – 3D Quantitative imaging

Z-Stacking at camera frame rate 

3D acquisition speed only limited by camera performance, i.e volume acquisition @ 75 image planes / second, full resolution 2048 x 2048 with sCMOS camera, CameraLink interface, trigger mode

Vibration free 3D acquisition

Samples  in a fixed / steady position during acquisition

No objective or stage move thanks to remote focusing principle

3D Add-on compatible with all microscopy techniques
