Sony announced a new camera today that features a 42 megapixel back-illuminated CMOS sensor. I’m not that interested in the camera, but the sensor sounds pretty intriguing. No back illuminated CMOS sensors have yet made it to the scientific imaging world that I’m aware of, but we’ve all been eagerly awaiting them. It’s not clear how well a monochrome version of this Sony sensor would perform for microscopy, but the prospect of a back-illuminated CMOS sensor is pretty tantalizing. The other sensor that Sony announced, a back-illuminated, stacked sensor, also looks pretty interesting, although I understand the details less well. As far as I can tell there are no data sheets for the sensors themselves.
While trying to learn more about these sensors, I also came across this interesting page from Chipworks, comparing sensors in different Nikon cameras and their specifications.
