National Optical & Scientific Instruments' 417TBL-10 Stereo Microscope is an affordable, yet feature-filled tool, especially designed for those in industry and education. Producing a three-dimensional, upright, unreversed image, this member of the 415 series is easy to work with. When a quick look at a specimen is needed - or more intricate work is demanded (like dissecting, or examining a circuit board), the 417TBL-10 doesn't confuse, providing the user with a 20x or 40x magnification in "correct" orientation.

Changing between the two magnifications is simple; just turn the objective turret for a smooth transition. The paired widefield 10x eyepieces sit at a 45° incline and feature diopter and interpupillary adjustments. They are also equipped with a reticle holder/retainer to accept a reticle with 2.3mm O.D. Additionally, the eyepieces sit on a 360° rotating viewing head for sharing.

The 417TBL-10 also features cool running fluorescent illumination. Both incidental and transmitted lights are 110V, 5W and can be operated using the 4-position light control. When it comes to focusing, the microscope uses rack and pinion focusing for precise adjustments. A slip clutch and tension adjustment protect the system from damage caused by over focusing or drift. There's also a post mount with a locking collar that accommodates different sized items on the stage.
