The National Optical & Scientific Instruments 155-MS Monocular Compound Microscope is an advanced model designed for use in high school labs. Highlights include a full size frame, 5W fluorescent illumination, crisp optics, and a lifetime warranty.

The DIN standard objectives include 4x, 10x, and 40xR lenses for 40x, 100x, and 400x magnification. A 3-hole objective turret facilitates smooth, precise changes. For student's comfort, the 155-MS also has a 45° inclined monocular with a widefield 10x eyepiece. The monocular can be rotated 360° for sharing with other students as well.

Other features of the 155-MS include a movable stage for focusing, and multiple safety mechanisms that protect the instrument from damage. Illumination for the microscope is provided by a 5 watt fluorescent bulb. This bulb produces virtually no base heat, and is rated at 10,000 hours.
