Case 1276 ยท Public preview
Surface Residues Can Produce an Orange-Peel Optical Appearance
Several lens surfaces exhibited an irregular orange-peel appearance, including one nominally unused comparison lens.

What the evidence preview establishes
The optical irregularity was associated with surface residues containing hydrocarbons together with variable mineral and salt deposits. Their presence on a nominally unused lens indicated that handling or assembly contamination was possible.
Why this case matters
When an optical surface develops an orange-peel appearance, compare it with a clean control and analyze both the broad film and discrete particles. Similar residue on an unused part should shift attention toward handling and assembly controls.
