Make it visible! button
If the microscope is so poorly adjusted that no image of the specimen is visible, this button can be used
to reset the microscope to a standard state in which the specimen is visible.
The following settings are adapted in this basic state:
Bio / Med stand:
− transmitted light illuminator is set to medium brightness (3 V)
− aperture diaphragm is opened
− TL shutter open, RL shutter closed
− Motorized condenser is switched to brightfield
− reflector turret is rotated to the nearest brightfield position
− Light path switching is set to 100 % vis
MAT (materials) stand:
− Reflected light illuminator (HAL 100 or LED) set to medium brightness
− TL shutter closed
− RL shutter opened
− Reflector turret in brightfield reflected light position (alternatively contrast module)
− reflected light luminous-field diaphragm opened
− reflected light aperture diaphragm opened
− Optovar turret in position 1: Optovar 1x
− Sideport in position 1 (100% vis)
− Baseport in position 2 (100% vis)
The nosepiece position (and, if entered, the objective) will be shown on the left of the status bar, the
halogen illuminator voltage on the right.
