Our component / drawing revision: [ ]
Assembly and mating interfaces: [ ]

Please review:
1. Ring drawing and lens-stack/barrel mechanical envelope
2. Material, thread specification, contact surface and final treatment
3. Quantities, cleanliness requirements and separate assembly approval procedure

Sample acceptance to agree:
1. Clear aperture: Define opening and clearance against the optical stack envelope.
2. Contact land: Specify retaining face, permitted edge condition and intended contact.
3. External thread: State pitch, class, usable length and final-finish gauging condition.
4. Spanner slots: Control tool engagement and edges that could release particles.
