The Scienscope SZ-PK5-AN SSZ-II Series Stereo Zoom Binocular Microscope is on a gliding arm boom stand with a fiber optic annular ring light that is designed to support large research grade microscopes. It has a smooth gliding motion and offers resistance to tip-over and vibration.
The SSZ-II Stereo Zoom Binocular Microscope is the most popular binocular microscope with high performance and durability that has been proven and time tested. It is made with the most advanced body construction and technology with a single spindle zoom, modularized gears, and fixed prisms. It also uses an isolated nylon-on-nylon gear system which increases the smoothness of the zoom, reduces martial fatigue, and protects the gears from other moving parts. This system is less likely to deteriorate over time due to the compatibility of the materials.
