The National Optical and Scientific Instruments 420-430PHF-10 Stereo Zoom Microscope provides you with an upright, unreversed three dimensional image that remains in focus throughout the zoom range. The microscope zooms from 10x to 40x, giving you a large viewing picture throughout the entire range.

The paired widefield 10x eyepieces sit on an inclined 45° head that rotates 360° for easy sharing. Each eyepiece features diopter adjustment, achromatic, color corrected lenses, and the ability to add optional auxiliary lenses.

The 420-430PHF-10 is halogen and fluorescent illuminated. An 80mm frosted glass, black and white contrast plate helps to bring specimens into focus clearly. The post mount permits up or down adjustment of the viewing head.
