Page 3: Introduction
Congratulations on the purchase of your new AmScope microscope head! This manual is designed for the SM745 series microscope heads (SM745B/T and SM745TP). The two base models of this series differ in that the -B models are binocular (two eyepiece ocular tubes), while the -T models are trinocular (two eyepiece ocular tubes with a third port on top for a microscope camera). -
Page 4: Safety Precautions
SM745 Manual Safety Precautions 1. As the microscope is a precision instrument, always handle it with care, avoiding impact or abrupt movement during transportation. Do not shake the package. 2. Do not place the microscope in direct sunlight or in high heat. Keep it indoors in a dry and clean place with temperatures between 32-100 degrees F (0-40 degrees C), and in maximum relative humidity of 85%. -

SM745 Manual Setting Up 1. Once you have placed your sample on the table or base below the objective, center the sample as best as possible. A slide is neither needed nor required for a stereo microscope, although they can be used if desired. If using a slide, use the stage clips to hold it in place. -
Page 11: Focusing
SM745 Manual Focusing 1. A stereo microscope’s focus differs from a compound microscope due to the lower magnification levels. Magnification and focal distance (working distance) are inversely related to each other, like a compound microscope, however the focal distance changes are far more drastic. -
