Product description The National Optical & Scientific Instruments Model 210 Compound Microscope is a cost-effective microscope, designed for use in schools. The 210's defining feature is the 45° inclined monocular, which sits on a viewing head that rotates 360°. Backing up this monocular would be its widefield 10x eyepiece and the DIN standard 4x, 10x, and 40xR objectives which supply 40x, 100x, and 400x magnification. In addition to the rotating head the Model 210 also features cool running LED illumination. This light produces virtually no heat and has a life rate at 50,000 hours. A base mounted on/off switch controls the light as well. Along with these helpful features the 210 also has focusing precautions, designed to protect the microscope from over focusing or other rough treatment. The slip clutch prevents damage from too much turning of the focusing knobs, while the safety rack stop prevents damage to specimen slides and objective lenses. Additionally, the tension adjustment eliminates stage drift. - Optical System
