4-60mm Manual Iris Diaphragm

Adjust the clear opening in a compatible optical assembly with an 18-blade manual iris diaphragm.

✅ Change the opening without replacing a plate - The iris mechanism varies the aperture across the described 4-60 mm range.

✅ Explore different optical settings - Manual adjustment lets you compare the effect of opening size in a matching experiment.

✅ Fit a defined mechanical envelope - An 82 mm outer diameter and 8 mm thickness provide dimensions for mounting design.

Put aperture adjustment into the optical path

An optical project may need a variable opening rather than one fixed hole. The iris provides that control as a mechanical component within the lens, illumination or observation arrangement.

Check mounting clearance and the optical design before purchase. Move the mechanism gently, avoid touching the blades and keep it clean and dry; this is not a complete camera lens or microscope.
