General description
Dissection and observation of macro specimens is more enlightening with a Jenco Stereo microscope. The large stage allows ample room for sample manipulation but still fits in a storage cabinet.
Their illuminated stands let you choose light from three directions - above, below or both, to help observe opaque or transparent samples. Solid, all metal focusing mechanisms will endure student use well beyond the five year warranty.
Teachers like them because the eyepieces are locked and don′t walk, the all metal frames are built to last and the low voltage bulbs last for hundreds of hours and are easy to replace. Even models with rechargeable illuminators are available.

What is the difference between achromatic, semi-planachromatic, and planachromatic objectives on a Jenco™ microscope?
1 answer-
Each type of objective is color corrected to a higher degree than the previous one. In everyday terms, achromatic objectives afford approximately 80% of the field of view in focus from the center out to the edges. Semi-planachromatic afford approximately 90% and planachromatic afford approximately 100%. The better the color correction, the more cost.

We recommend only those models with trinocular heads because they are more stable and we have adapters to fit the trinocular tube, not the eyepiece, Jenco Model BC-311 (Sigma nos. Z735086 for 115V or Z737062 for 220V).
