We have been using 10 ms exposure and getting 100 fps and I’m just as confident in the data at 100 fps with the Prime 95B as with 10 fps with the EMCCD.

Dr. Ehud Isacoff, Director, Helen Wills Neuroscience Institute, UC Berkeley


The field of view of the Prime 95B is >2.5x bigger than our previous camera, allowing us to image more than twice the amount of data in a single imaging session and the high sensitivity of the Prime 95B dramatically reduced the exposure time needed to collect our images.

Marc Freichel, PhD, Prof., Heidelberg University


The combination of increased sensitivity and signal to noise ratio meant the 95B was the best camera choice.

Dr. Philippe Bastin, Institut Pasteur
