            Small fluorescent screen\/binoculars<\/h3>\n\n\n

            💡 If precise observation or focusing is required, binocular magnifiers and a small fluorescent screen can be used (magnification factor x10).<\/p>\n\n\n

              \n
            1. Push down the small fluorescent plate lever on the right side of the lens barrel.\n
                \n
              1. A small fluorescent screen is inserted into the electron beam path.<\/li>\n<\/ol>\n<\/li>\n\n\n
              2. Move the binoculars in front of the fluorescent screen.<\/li>\n\n\n
              3. Focus the binoculars on the small fluorescent screen.\n
                  \n
                1. While looking through the binoculars, move the focusing knob to focus on the center point of the small fluorescent screen.<\/li>\n\n\n
                2. If the left and right focal points are different, adjust by rotating the eyepiece.<\/li>\n<\/ol>\n<\/li>\n\n\n
                3. [TC: TEM System Task Bar: Screen] Brightness check (if necessary)\n
                    \n
                  1. Displays beam current density on small fluorescent screen<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n\n\n

                    beam stopper<\/h3>\n\n\n

                    💡 Can be used to block transmitted waves in electron diffraction or as a landmark during image observation.<\/p>\n\n\n

                      \n
                    1. Turn the beam stopper lever on the left side of the lens barrel.\n
                        \n
                      1. A beam stopper is inserted into the electron beam path.<\/li>\n\n\n
                      2. If necessary, turn the lever slightly to fine-tune the position.<\/li>\n<\/ol>\n<\/li>\n\n\n
                      3. If the stopper movement is too large and fine adjustment is difficult, move the beam.<\/li>\n<\/ol>\n\n\n

                        screen operation<\/h3>\n\n\n

                        💡 Open and close the large fluorescent screen when using a bottom mount camera (CCD camera).<\/p>\n\n\n

                          \n
                        1. An enlarged image or electron diffraction pattern is displayed on a fluorescent screen.<\/li>\n\n\n
                        2. Lower the magnification and camera length.\n
                            \n
                          1. The field of view of the camera is narrower than that of the screen.<\/li>\n<\/ol>\n<\/li>\n\n\n
                          2. Adjust brightness (darken)\n
                              \n
                            1. Lowering the magnification increases the current density and may damage the sensor.<\/li>\n<\/ol>\n<\/li>\n\n\n
                            2. Insert beam stopper (if required)<\/li>\n\n\n
                            3. [PANEL R: F4] Raise the screen (90 degrees)<\/li>\n\n\n
                            4. [PANEL R: F4] Lower the screen (0 degrees)<\/li>\n<\/ol>\n\n\n

                              💡 Can also be operated from the TEM center<\/p>\n\n\n\n\n
