Zoom lenses

7:1 Modular C-Mount Zoom

With this exceptionally reliable zoom lens kit, you will find a solution wherever magnification needs to be adjusted quickly and flexibly. All tubes (pipes) have a diameter of 35 mm. Combine your solution with the adapters, tubes, zoom modules, objectives and illuminators needed for your application.

Selection guide

The configuration of your system is very simple:

From the overview diagram, you can quickly see the possible component combinations.
Determine your field of view (FoV).
Select the necessary working distance (WD).
Go to the magnification table and select your tube and objective. Tip: Choose a larger magnification rather than a longer tube.
Find your other components in the overview diagram, such as grid of the zoom, focus modules, illumination and other adapters.
Note: The magnetic clutch should not be combined with the 58/66mm ring light.
