National 420T-430PHF-10 Overview

  • 1Description

The National Optical & Scientific Instruments Model 420T-430PHF-10 Stereoscopic Microscope provides the user with a large upright, unreversed image that appears clear and accurate throughout the 10-40x zoom range. Optional eyepieces and auxiliary objectives expand the magnification range and working distances.

Designed with paired widefield 10x eyepieces, the microscope also has a trinocular port that accepts video or SLR adapters (included). The paired eyepieces sit at a 45° incline on the viewing head which rotates 360° for sharing. Focusing is done using large dual knobs with a slip clutch to prevent damage from over turning. Additionally, a tension adjustment eliminates focus drift.

Illumination for the 420T-430PHF-10 is provided by a halogen top light and a fluorescent bottom light. Base mounted controls allow the user to choice top only, bottom only, or dual illumination. The stage consists of 80mm frosted glass and reversible black/white plastic contrast plates. A blue filter transmits light, while locked-on stage clips keep specimens in place.

In addition to the above features, the 420T-430PHF-10 is constructed of an all-metal frame with an enamel finish. The post mount has a locking support collar which permits up or down adjustment. The microscope is also backed by a lifetime warranty, ensuring its tenure in your facility for years to come.
