National 163-ASC overview

  • 1Description

The National Optical & Scientific Instruments 163-ASC Trinocular Compound Oil Immersion Microscope is a mid-range microscope that offers up a bevy of features. Designed for university and laboratory use, the 163-ASC's defining factor is the ASC objective lenses that comprise the heart of the instrument's optical system. Providing 40x, 100x, 400x, and 1000x magnification, these lenses are the basis of an accurate and precise microscope.

Utilizing those objectives requires either using the 30° inclined widefield 10x eyepieces or the verticle tube, which removes to allow optional SLR or video adapters. All three sit on top of the 360° rotating head, which enables sharing with other students or research partners.

Halogen illumination supports viewing of specimens. The 12V, 20 watt bulb has a variable rheostat control, an illuminated on/off switch, a heavy-duty 3-wire grounded electrical system and plug, and a 0.5A time delay fuse. When it comes to focusing, the 163-ASC provides users with coaxial coarse and fine focusing. Safety mechanisms work to prevent any damage that could result from over focusing or stage drift.
