Capturing low-dose images, in-situ video, and diffraction data with the Metro counting camera

Gatan’s latest counting camera, Metro, produces excellent results at low dose rates and low to moderate accelerating voltages (60 – 200 kV). In this webinar, we show images from zeolites and MOFs, as well as diffraction patterns and 4D-STEM datasets from 2D materials. We demonstrate the in-situ capabilities of the camera, which can capture video datasets at up to 41 frames per second at full 2k x 2k resolution. We also demonstrate how, at the low dose rates so essential for imaging many materials without destroying them, 2k x 2k counted images taken with the Metro are preferable to 4k x 4k images acquired with the scintillator-based OneView camera. Finally, we’ll show how the camera interface was designed for ease of use without sacrificing the power and flexibility provided by DigitalMicrograph software.
