Crisper and Cleaner Images

New Photo Multiplier Tube (PMT) and Secondary Detector

Overall imaging in the Secondary mode of operation is improved.

New Photo Multiplier Tube to brings the gain of the SED back to its original specification (Over time, photo multiplier tubes lose their gain).

Improved Secondary Detector design with larger surface area secondary detector increases the overall gain by 50%.

Improved gain increases the signal to noise ratio and allows you to operate at smaller beam diameters, which provides crisper and cleaner images at higher magnifications.
