Sony IMX335 sensor
The sensor is 5.1 megapixels (that's about 2.5x higher resolution than Full HDMI is!) or 8.3 or 12 MP. It is well known from astronomical applications where really little light is available. The high sensitivity enables shorter exposure times and thus a significantly faster frame rate. The image no longer jerks, even if you record video or just want to move the microscope's stage, but is displayed in real time.
On-board electronics
There is a sensational idea in the completely redesigned board electronics, which enables fast image transmission in high resolution despite USB2.0: The raw image data is not simply transmitted as with other microscope cameras, but is pre-compressed in the camera housing and processed by the ToupView software the computer unzipped again. In this way the "bottleneck USB2.0" is avoided and a multiple frame rate can be achieved!
