Used to increase the effective focal length of an installed C-mount lens when a longer working distance or tighter field of view is required.
Avoids replacing the full lens assembly when additional magnification is needed.
Helps adapt an existing lens for closer-detail inspection of small parts on production lines by multiplying lens focal length.
Improves imaging scale for small-feature inspection without changing camera hardware.
Provides a simple mechanical-optical retrofit option for tuning the optics of legacy C-mount camera systems.
Enables optical adjustment in legacy installations without redesigning the camera or mounting interface.
