Overview
  • 1Description

The Model 163 Trinocular Compound Oil Immersion Microscope from National Optical and Scientific Instruments is a high-end instrument designed with university and laboratory use in mind. Boasting a large number of features, including a lifetime warranty, the 163 is sure to be an asset to your institution for many years to come.

The optical system of the 163 is centered around the trinocular viewing head which is comprised of 30° inclined binocular eyepieces and a vertical monocular tube. The entire viewing head rotates 360° for easy sharing with other students or co-workers. Removable of the vertical tube permits mounting of optional DSLR or video adapters for documentation of work.

The DIN standard oil immersion objectives include the following: 4x, 10x, 40xR, and 100xR. These objectives provide magnification of 40x, 100x, 400x, and 1000x. A quad objective turret is ball-bearing mounted for smooth, precise positioning of objectives and has textured rubber knurling for an easy grip.

Illumination for the 163 is provided by a 12V, 20 watt halogen bulb with a variable rheostat control. The illumination is controlled by an on/off switch and a 3-wire grounded cord and plug. Focusing is provided via coaxial coarse and fine controls. The coarse control has tension adjustment, while fine is graduated.

Another check in the plus column for the 163 is its large 5.5 x 5.25" stage. The specimen stage is ball-bearing mounted and features low-position coaxial controls, with movements in gradations of 0.1mm. Additionally, the 1.25 N.A. Abbe condenser has rack and pinion focusing, an iris diaphragm, and a swing-out filter holder with clear, blue, green, and yellow filters.
