  2. On the Jenco™ microscope, what is a light blue filter used for?

    1 answer

    1. Blue filters are used to change the color of light from the bulb to a cleaner white light.

      Helpful?

  3. 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?

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

    1 answer

    1. There is no difference.  Those are different names for the same microscope.

  5. What is a LWD objective?

    1 answer

    1. A Longer Working Distance for when you can't get close enough to focus on what you want to see. They are included with Jenco brand inverted microscopes.

      Helpful?

  6. 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.

      Helpful?

  7. What is a compound microscope?

    1 answer

    1. A microscope with one light path going through compound parts providing high magnification (40x to 1,000x or more). Jenco Model BC-211 (Sigma nos. Z734977 for 115V or Z736945 for 220V) for example.

      Helpful?

  8. 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.

      Helpful?

  9. What Jenco™ microscopes can be used wiith video or digital camera equipment?

    1 answer

    1. 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).

      Helpful?

  10. What do the numbers on the outside of the barrel of the objective on a Jenco™  microscope stand for?

    1 answer

    1. They identify five specifications: magnification (60X), aberration correction (PlanAchro), coverglass thickness recommended (0.17), numerical aperture (.85), and specialized optical properties (Phase, (PHP), fluorite (FL), etc.
