Key Features

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.


Superior Background Quality
The Prime BSI Express features Pattern Noise Reduction Technology and Correlated Noise Reduction Technology to ensure that it delivers clean, pattern-free images with minimal pixel defects, delivering improved image quality in low light conditions.

Customer Stories
Cleared Fish Brain OpenSPIM

“The small pixel size of the Prime BSI Express combined with the relatively large sensor and high speed is a big advantage.”
Live Cell Microfluidics

“We wanted a robust camera that produces clean images, with not a lot of noise, that can go down to low millisecond exposure without losing too much brightness. The Prime BSI Express does it all.”
Sub-cellular Oblique Plane Microscopy

“The [Prime BSI Express] gives us better gain variation and raw image quality compared to other sCMOS-style cameras.”
