Why Can't I Change the Filter Turret Position with My Leica Microscope Using Volocity?

If the filter turret does not move to the transmitted light position when requested in Volocity, this is likely due to the Contrast Mode setting on Leica microscopes. Leica microscopes have contrast modes such as "Fluorescence," "DIC," or "DIC and Fluorescence," which can limit software control over the filter turret position.

Steps to Resolve the Issue:

  1. Check and Adjust the Contrast Mode:

    • Ensure that the Contrast Mode is set to the desired setting (e.g., "DIC and Fluorescence" for compatibility with both transmitted and fluorescent light paths).

  2. Include the Contrast Mode in the Lightpath:

    • Double-click on the desired lightpath button in the Video Preview.
    • In the Device Checklist, ensure that Contrast Mode is checked.
    • Click Save to update the lightpath settings.

If necessary, you can manually move the filter turret to the transmitted light position using the buttons on the microscope.
