  • SEM Resolution
  • Sample Requirements
    • Samples must be compatible with high vacuum, i.e., clean and dry. Samples should be handled with tweezers or gloves.
    • A large range of sample sizes will fit into the chamber up to a limit of about 6 inches in diameter and/or ~ 2 inches tall. You may not be able to access the entire area of a very wide sample. Ask for assistance if you are approaching the limits.
    • Samples need to be conductive. Semi-conductors are OK. Non-conductive samples should be coated with a conductive layer. Conductive samples surrounded by a non-conducting medium should be provided a conductive path to the SEM stub.
