The facts on the card
The card carries these facts from its Wikipedia article.
- The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition.
- The electron beam is scanned in a raster scan pattern, and the position of the beam is combined with the intensity of the detected signal to produce an image.
- In the most common SEM mode, secondary electrons emitted by atoms excited by the electron beam are detected using a secondary electron detector.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Scanning electron microscope article was read about 140,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 86: each hit it takes is cut by 34 %.
How to get Scanning electron microscope
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
