What to do if my Zeiss Axioskop 2 plus has dirt or dust in the field of view?
- A

  If you notice dirt or dust in the field of view of your Zeiss Microscope, it could be due to a few reasons. First, ensure the condenser is correctly focused and the condenser lens 0.9 is switched correctly. Also, check that the aperture diaphragm opening isn't too small; adjust it according to the 2/3 rule or the specific features of your specimen. Finally, inspect and clean the optical surfaces of your objectives, eyepieces, condensers, filters, or the specimens themselves to remove any dirt or dust.

Why is my Zeiss Axioskop 2 plus image brightness inhomogeneous and not entirely visible?
- M
  Michael SmithAug 17, 2025
  Uneven brightness or incomplete visibility in your Zeiss Microscope's field of view can stem from several factors. The vis/fot pushrod on the camera tube might not be in the correct position; ensure it's fully in the end position. Check that the nosepiece with the objective is correctly clicked into place. Also, verify that the condenser, aperture diaphragm, and luminous-field diaphragm are properly set (adjusted, centered, and opened). Lastly, confirm the filter is correctly inserted in the filter mount.

Why does my Zeiss Axioskop 2 plus have low resolving power and poor image contrast?
- J
  John JonesAug 20, 2025
  Low resolving power and poor image contrast in your Zeiss Microscope can arise from several causes. Ensure the aperture diaphragm opening is correctly set according to the 2/3 rule or specimen features. Focus the condenser correctly and properly switch the condenser lens 0.9. Use standardized cover slips with a thickness of 0.17 mm. If using immersion objectives, apply immersion oil 518 N from Carl Zeiss. Remove any air bubbles in the immersion oil and clean the front lens of any dry objective if it has immersion oil on it. Also, set the corr. ring to the correct cover slip thickness. Finally, ensure all optical surfaces of objectives, eyepieces, condensers, or filters are free from dirt or dust.

Why does my Zeiss Axioskop 2 plus lamp flicker or have unstable brightness?
- L
  Lauren MyersAug 25, 2025
  If the 12 V 100 W halogen lamp in your Zeiss Microscope flickers or has unstable brightness, it might be nearing the end of its average lifespan, so consider replacing it. Check the line cable for correct connection or breakage, and replace if necessary. Also, ensure the pins of the 12 V 100 W halogen lamp are correctly inserted into the receptacle.

Why is my Zeiss Microscope image asymmetrically blurred?
- R
  Robert FrenchAug 27, 2025
  Asymmetrically blurred images, where one side is in focus but the other isn't, on your Zeiss Microscope can be due to a few reasons. Check that the condenser is correctly set. Ensure the nosepiece is properly clicked into position. Also, make sure the specimen is correctly inserted and clamped in position on the mechanical stage.

What to do if my Zeiss Axioskop 2 plus Microscope has great focus differences after objective change?
- M
  Mary FlynnAug 30, 2025
  If you experience significant focus differences after changing objectives on your Zeiss Microscope, it could be due to a few reasons. Ensure the focusing eyepieces are set to the appropriate ametropia. Verify that the objective is fully screwed in until it stops. Also, check if the tube lens is either not integrated or integrated superfluously; correct as needed.

Why can't I combine left and right fields of view into an image in my Zeiss Axioskop 2 plus Microscope?
- J
  Jeffrey TaylorSep 3, 2025
  If you're unable to combine the left and right fields of view into a single image with your Zeiss Microscope, the interpupillary distance of the binocular tube might not be set correctly, so adjust it accordingly. Also, ensure that the focusing eyepieces are set to the appropriate ametropia.

Why am I experiencing eye-fatiguing microscopy with my Zeiss Axioskop 2 plus Microscope?
- E
  Eric BradleySep 6, 2025
  Eye fatigue during microscopy with your Zeiss Microscope can occur due to several reasons. Ensure the interpupillary distance of the binocular tube is correctly set. Also, verify that the focusing eyepieces are adjusted to the appropriate ametropia. Adjust the lamp voltage or insert a conversion filter to achieve acceptable image brightness. If the binocular tube is optically or mechanically misaligned, it may require professional service.

Why can't the lamp voltage of my Zeiss Axioskop 2 mot plus be regulated?
- E
  elizabeth85Sep 9, 2025
  If the lamp voltage of your 12 V / 100 W halogen lamp cannot be regulated for the Axioskop 2 mot plus, it might be because the control for light intensity is in the stop position. This causes the light manager to regulate the intensity to the preset or stored value. To resolve this, move the control shortly out of the stop position, which should allow the light intensity to be set as usual again.
