01

A conservative process.

Step 01

Requirement review

The project requirement is reviewed before any component work begins.

Step 02

Component preparation

Component-preparation requirements are defined for the selected design.

Step 03

Assembly

Iris blade mechanisms are assembled according to the reviewed requirement.

Step 04

Dimensional and movement checks

Finished dimensions and aperture movement are checked against the agreed specification.
