Abstract：Objective: To exploit the designs of digital imaging apparatus for transmission electron microscope(TEM) for better performances. Methods: Analyzing the characteristics and drawbacks of various kinds of digital imaging apparatus for TEM for conceiving new designs of digital imaging apparatus for TEM. Results: Four basic kinds of digital imaging apparatus for TEM inlcuding side mounted lens-coupled, side mounted fiber-optical coupled, bottom mounted lens-coupled, bottom mounted fiber-optical coupled are newly designed. A prototype of bottom mounted lens-coupled digital imaging apparatus for TEM with large field of view(FOV) is developed and applied to practice.Conclusion: The newly designed bottom mounted lens-coupled digital imaging apparatus for TEM has a unique structure and can best suit applications in life and medical science where large FOV matters.
