DESCRIPTION

The National Optical model 167 monocular compound microscope with semi-plan optics is superior in design and performance to most other microscopes. The quality construction and engineering make it ideal for university, laboratory, and professional use, or for families who enjoy microbiology and want the highest quality for viewing cells.

The higher-quality semi-plan DIN optics provide superb optical clarity at 40, 100, 400, and 1000x magnification with 80-85% flatness of field. 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 167-SP, lifetime warranty.
