Alpine Direct Detection Cameras

Alpine^® is the world’s first direct detection camera series to democratize cryo-electron microscopy (cryo-EM) imaging. By enabling the acquisition of high-resolution structures on 80 – 200 keV microscopes, the Alpine series allows routine cryo-EM research on more affordable, workhorse instruments and expands its usefulness to the larger research community.

• Two models available to match the field of view with your application needs:
  Alpine (1124) – Turns 80 – 200 keV screening microscopes into data-collection microscopes with single-electron counting capabilities
  Alpine Vista (1125) – Maximizes imaging throughput for your high-performance microscopes with a large FOV of 5,760 x 4,092 pixels
• Delivers a detective quantum efficiency (DQE) up to 2.4-times the performance of scintillator-based cameras
• Makes the 2D classification of small molecules possible while improving macromolecule reconstructions
• Streamlines your workflow and detects failures early to produce better structures, faster
• Real-time counting ensures there is no compromise between data collection speed and quality
