Test internal lenses:
Samples of 9 Semi finished of different bases (4 shades Transition Brown and 5 Transition grey)
Value of transmission:
Transitions Brown grey
Value in the clear State 91% 92%
Value in the dark state 16% 17%
! Dark state value measured after exposure under UV lamp for 2 min (non-optimal value)
Control of the Semi finished:
The general appearance is OK but too little shuffleboard for compare the technical data (average RADIUS, thick Center)
! A problem of cylinder on a basis was found (Base 5 grey)
! Visible tensions in the tensiscope in the semi-finished
Machining:
2 pairs of glasses made:
-1st: 2 single-vision glasses (Brown T7 and T7 grey)
-2nd: 1 glass FF (Neo perfect) and progressive 1 FF (Synchrona)
No scratches visible suite Toro-X or polished automatic switching.
Aspect control and power output of production
! See at the level of the instalment of the glass which is toothed (client impact?)
Treatment:
Hardened: choice of lacquer 1.6 + oven 120 - identical lacquer used for the 'classics' Tribrid
(Validated with treatment)
Treatment: A.R.I and A.R.2 made
No particular point in output processing. Abrasion and pullout tests are consistent.
Editing:
Testing of clipping on 2 glasses of different thickness (E. edges 10/10 and 25/10)
No problem for grinding and trimming of the glasses. Drilling ok.
