Ultra-sensitive low-noise detection

No matter the wonders delivered by our AOD light-steering technology, the quality of your experiments ultimately depends on your photon flux and signal to noise ratio.
That is why Karthala System has invested in last-generation detectors and high-precision custom electronics. Combined with optimized photon collection, shot-noise limited fluorescent signals will give you the sensitivity you always craved for.
