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.

  • Affordable
  • Portable
  • Durable
  • Easy to use
  • Five Year warranty

  2. Can you use a 35mm camera with your Jenco™ microscopes?

  3. What is the difference between achromatic, semi-planachromatic, and planachromatic objectives on a Jenco™  microscope?

    1 answer
    1. 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.

  4. What does the working distance on a Jenco™ microscope refer to?

    1 answer
    1. The working distance is measured from the end of the objective to the top of the specimen when the specimen is in focus.

    1 answer
    1. The part of the microscope where the objectives are attached. It is either reversed, with the objectives pointing away from the operator giving better access to the sample, or standard with objectives pointing toward the operator.

  8. What is a Reticle on a Jenco™ microscope?

    1 answer
    1. A group of lines, shapes, circles, or angles that are inserted in the eyepiece (usually on a disc) that provide either a standard of measurement or a focal point for the observer.

  9. Why use immersion oil on a Jenco™  microscope?

    1 answer
    1. If an objective is designed to use oil, you must use oil to get an acceptable image. Oil provides an improved path for the image to travel between the specimen and the objective.
