Leica DM IRB manual Trinocular tube HCI 3T22, Side of the tube

To correct defective eyesight:

●Look through the right-hand eyepiece tube with your right eye and sharply focus the specimen with the fine drive.

●Then look at the same area of the specimen with your left eye and rotate the left eyepiece tube until you obtain a sharp image. Do not use the fine drive for this.

●If using eyepieces with adjustable eyelenses, do not compensate for defective eyesight by adjusting the eyepiece tube, but by adjusting the eyelens of the eyepiece.
