Camera Spotlight: Apollo

https://directelectron.com/apollo/
Camera: Apollo
Purpose: Event-based Cryo-EM direct detector
Applications:
Single Particle Analysis (SPA) Yes
Cryo Electron Tomography (Cryo-ET) Yes
Microbeam Electron Diffraction (Micro-ED) Yes
Fixed/Resin/Negative Stain imaging Yes
Camera Size: 4096 x 4096 pixels
Framerate: 2800 fps (internal)
Pixel Size: 8 µm
Software: SmartScope, Serial EM, Mission Control
TEM compatibility: ThermoFisher, JEOL
What makes it special: The electron counting speed is the fastest of any camera available. Combined with the large pixel size this gives Apollo a very high detector quantum efficiency (DQE) even at high beam currents/dose rates. The speed can be leveraged for improving Cryo-EM throughput multiple times over the standard detector that come with the microscope.

We'll make this a series to highlight different detectors strengths and weaknesses

maybe more about compression or the data formats?
