High signal-to-noise TEM imaging with ClearView Frame Control mode
Enabling Frame Control mode allows users to better leverage the full dynamic range of the camera and maximize the signal-to-noise in acquired images by reducing the camera framerate and minimizing the total readout noise in an image. The left and middle images show a 2 s image acquisition captured at 4k x 4k resolution and 50 fps. These images provide high levels of detail from the semiconductor sample being imaged. The right image utilizes Frame Control mode to capture a 2 s image at 4k x 4k resolution and 1 fps and shows the same inset area. This image has improved signal-to-noise better shows subtle differences in contrast, and better resolves interfaces in the material.
