The National Optical & Scientific Instruments DC5-163 Compound Biological Microscope is an impressive tool for scientific inquiry. More than just a feature-filled microscope, the 163 also has a built-in 2Mp digital camera for viewing and preservation of images.
The optical system of the microscope centers around DIN achromatic 4x, 10x, 40xR, and 100xR oil immersion objectives. All are achromatic, parfocalled, parcentered, and color-coded. Widefield 10x eyepieces sit at a 30° incline on the binocular head. Additional features include dual diopters, interpupillary adjustment, and 3-position sliding rod.
Halogen illumination lights specimens for a clear and accurate view. Focusing is rack and pinion, with coaxial coarse and fine focusing controls. Safety features such as a slip clutch, a tension adjustment, and a safety rack stop ensure that the system does not sustain damage.
