The National Optical and Scientific Instruments Model 162 Compound Microscope is a high-quality model, designed for use in universities and laboratories. Boasting a wide number of features, including oil immersion objectives and a lifetime warranty, the 162 is up to the tasks of education, research, and more.
The optical system of the 162 is based around 4 DIN standard oil immersion objectives, including 4x, 10x, 40xR, and 100xR. A 30° inclined binocular viewing head, with widefield 10x eyepieces and a pointer (in one eyepiece), rotates 360° for easy sharing. A quad objective turret that is ball-bearing mounted aids in precise positioning of objectives and features rubber knurling for an easy grip.
The 162 is illuminated by a 12V, 20 watt halogen light. The convenient on/off switch and a 3-wire grounded cord and plug ensure conservation of energy and ease-of-use. The light illuminates the specimen, which sits on a large 5.5 x 5.25" stage, which bears multiple features, including low-position coaxial controls.
