Spinning diskThe 3i Marianas is a CSU-X1 A1 Spinning Disk Confocal attached to a Zeiss Axio Observer 7 microscope with a range of long working distance lenses including a 63x water immersion objective. The system is optimized for speed and features a Hamamatsu ImagEM X2 back-thinned EM CCD camera with 512 x 512 pixels and capture speed up to 70 fps. It also has an Ablate!™ 532 module with 532nm pulsed laser for photo-activation and ablation and a VectorM™ VIS High Speed Point Scanner for photomanipulation techniques including FRAP, photoactivation and photoablation.
