The Model 104 Compound Microscope from National Optical & Scientific Instruments Inc. is a budget-friendly way to explore the world around you. Designed for students, the Model 104 features 40x, 100x, and 400x magnification. Helping you to see your specimens with ease are the three mounted objectives: 4x, 10x, 40xR. The 10x eyepiece has a revolving pointer and is inclined 45° for easy viewing. Additionally, the head rotates 360°.

Illumination is provided by a 115V built-in bulb, and the on/off switch on the base provides easy control. Oversized focusing knobs provide the user with the ability to focus between normal coarse and fine focus ranges, while the slip clutch prevents damage to the focus mechanism - a general hazard when students are concerned. Another way in which the microscope stays strong against abuse and daily wear and tear is its rugged cast metal body.
