Key Features

Prime BSI Express graph

Sensitivity

By bringing the light in from the back of the sensor, photons land directly onto the light receiving surface, maximizing light collecting capability.

The Prime BSI Express combines 95% quantum efficiency with the low 1.0 e- read noise CMS mode to deliver the most sensitive camera based on sCMOS technology at over 40 frames per second.

Compact Form Factor

The Prime BSI Express is a compact 78mm x 78mm x 90mm with optimized cooling for the size, ideal for integration into new or existing configurations.

Interface and Integrate

Interfacing and integration is simple with the Prime BSI Express, which uses USB 3.2 Gen 2 for truly uncomplicated connectivity.

Our standard PVCAM driver can be easily installed in Windows operating systems to get the Prime BSI Express running in minutes.

Resolution and Pixel Size

The Prime BSI Express features 6.5 µm pixels, the accepted standard for most live cell applications.

This pixel size provides highly detailed images across the imaging plane and is most suitable for the broadest range of magnifications.
