The National Optical & Scientific Instruments DC5-163-PH Compound Biological Microscope is a high-quality instrument, designed for use in research environments. In addition to the microscope's many features there is a built-in 2Mp digital camera for viewing and manipulation of images.
The optical system of the DC3-163-PH is built around the 4x, 10x, 40xR, and 100xR DIN plan phase oil immersion objectives. The other features include binocular widefield 10x eyepieces, inclined at 30°, a revolving pointer, dual diopters, interpupillary adjustment, and a 3-position sliding rod to direct light.
Illumination for the DC3-163-PH is halogen, with a variable rheostat control. The illuminated on/off switch, a 12V DC power converter, and a 3-wire grounded cord and plug all ensure the safety of the illumination system and its ease of use. When it comes to focusing, the microscope uses rack and pinion focusing with a number of safety features to protect the system from damage.
