DESCRIPTION

The National Optical Model 168 microscope with semi-plan optics combines superior design and performance with a binocular head for enhanced image perspective and viewing comfort. It is an ideal microscope for university, laboratory, and professional use, or for families who want the best quality for viewing cells.

This compound binocular microscope provides superb optical clarity with higher-quality semi-plan DIN optics. The precision coaxial focusing and low-position coaxial stage controls are a pleasure to use and deliver smooth, reliable performance. Other features like the reverse position objective turret facilitate slide changing and ease of operation. The bright 3-watt LED lighting with variable intensity control, 1.25 N.A. Abbe condenser, and iris diaphragm with swing-out filter holder provide great contrast control. Order immersion oil for 1000x objective. National Optical model 168-SP, lifetime warranty.
