The National Optical & Scientific Instruments DC5-163-P Compound Biological Microscope features a built-in camera and numerous features, making it ideal for institutional research. The defining feature that sets this model apart from the others in the series is DIN plan achromatic objectives. The 4x, 10x, 40xR, and 100xR objectives are oil immersion optics. All are parfocalled, parcentered, and color-coded.
Other highlights of the optical system include widefield 10x eyepieces set at a 30° incline on the viewing head. The eyepieces also feature a revolving pointer, dual diopters, interpupillary adjustment, and a 3-position sliding rod that direct light.
The DC5-163-P has 12V, 20W halogen illumination, for making specimens as clear and accurate as possible. The 12V DC power converter operates on 100-240V current without need of an additional transformer, while a 3-wire grounded cord and plug ensure safe use.
When it comes to focusing, the DC5-163-P utilizes the rack and pinion method with coaxial coarse and fine focusing controls. Safety features that prevent damage to the system include a slip clutch, a tension adjustment, and a safety rack stop. Additionally, the microscope comes with a lifetime warranty. The camera has a 1-year warranty.
