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

Questions

1–10 of 39 Questions  

  1. What is the difference between a Stereo and a Dissecting microscope?

      Helpful?

  2. What is an Iris diaphragm on a Jenco microscope?

    1 answer

    1. The piece on the specimen side of the condenser that controls contrast and depth of field.

      Helpful?

  3. Why do some objectives on a Jenco™  microscope have retractable lenses?

    1 answer

    1. This feature provides protection against damage caused by a collision of the objective and the slide.

      Helpful?

  4. What is a Nosepiece or turret on a Jenco™  microscope?

    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.

      Helpful?

  5. 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.

      Helpful?

  6. Do Jenco™ inverted microscopes use oil objectives?

    1 answer

    1. No, because the objective is below the slide and the drop of oil could only sit on top of the slide.

      Helpful?

  7. Do your Jenco™ microscopes come with rubber eyecups?

    1 answer

    1. Yes.

      Helpful?

  8. On a Jenco™  microscope, what does Kohler Illumination do?

    1 answer

    1. Kohler illumination produces an even field of illumination over the whole specimen.

      Helpful?

  9. What is a Stage or Mechanical stage on a Jenco™  microscope?

    1 answer

    1. A flat plate for placing the slide/specimen with controls to easily move the sample both vertically and horizontally in small increments.

      Helpful?

  10. What is a Stereo microscope?

    1 answer

    1. A microscope that uses two light paths to give a 3-D view of a large specimen.  Mainly used for macro sized or solid samples.  Limited magnification range, 10x to 200x.
