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. </p> <p><strong>Built to last </strong> Precision CNC machined parts assembled to leading industry standards. Extends the life of the microscope and lowers service costs. </p> <p><strong>User-friendly & Ergonomic </strong> High point, lockable eyepieces and ergonomically located zoom control. </p> <p><strong>Proven Body Design </strong> Scienscope prisms are housed with the body of the microscope, and do not move with eyepieces. This design protects the prisms and eliminates the chance of misalignment caused by the prisms.Scienscope microscopes use an external nylon-on-nylon gear system. This increase the smoothness of the zoom and protects the gears from other moving parts. This system is less likely to deteriorate over time due to the compatibility of the materials. Notice how the gears are housed away from all other internal mechanisms.Scienscope microscope use advanced technology, Single Spindle Zoom design, which allows for a smooth zoom and control that is superior to many of competitors. This revolutionary design has two huge advantages. First, the objective cannot move independently of each other; therefore, it is less likely to cause a misaligned or double image. Secondly, the zoom knob is extremely smooth, allowing the user to maintain the vision trough eyepieces while zooming. </p>
