Unbeatable X-ray Detection

At Proto, we always choose the best possible x-ray detection systems for our equipment, which is why all of our x-ray crystallography systems are equipped with true photon-counting detectors. These detectors directly capture x-ray photons and convert them into an electrical signal. This direct conversion is advantageous because it yields zero dark noise, zero readout noise, high dynamic range, and excellent signal to noise. With our high-quality photon-counting detector options, you don't need to worry about detector saturation, allowing you to focus on your data.

We also offer CdTe sensors for the highest quantum efficiency with harder wavelengths.
