Scientific CMOS, EMCCD and CCD Cameras

High Resolution BSI Scientific CMOS
Prime BSI Express is designed on a compact platform optimizedfor integration and delivers the perfect balance between highresolution imaging and sensitivity with an optimized pixel
design and near perfect 95% Quantum Efficiency to maximize
signal detection.
A 4.2 Megapixel camera with 6.5μm pixels, it captures highly
detailed images with great quality while acquiring data at highframe rates with a convenient but capable USB 3.2 Gen 2interface. This ensures that all data is collected and no event
goes undetected.
This perfect balance in performance makes the Prime BSI Express
the most versatile imaging camera for system integration with:
