Questions

1–10 of 39 Questions  

  1. 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.

      Helpful?

  2. 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?

  3. 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?

  4. What is a Parfocal on a Jenco microscope?

    1 answer

    1. Parfocal means the center of your specimen will stay in focus as you change magnification.

      Helpful?

  5. 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?

  6. 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?

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

    1 answer

    1. We do not suggest using a 35mm Camera as we have found that a digital camera provides a clearer picture.

      Helpful?

  8. On the Jenco™ microscope, what is a green filter used for?

    1 answer

    1. Since achromatic objectives are best corrected spherically for green light, a green filter improves the performance of your achromatic objectives.

      Helpful?

  9. 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.

      Helpful?

  10. What is a Micrometer on a Jenco™ microscope?

    1 answer

    1. The same as a reticle, only more specific to a group of lines used as a scale for measuring.
