All our Optolite™ filter windows are subject to our detailed Quality
Assurance procedure which involves 100% visual inspection of all
lenses before dispatch. Each lens, when passed by inspection, is
laminated with a protection film on both front and rear surfaces
to give protection during transfer and from accidental damage during
assembly.
All our Optolite™ filter windows are assessed for the following:
• Scratches
• Inclusions
• Dimensions (to specified tolerances)
• Mesh angle
All windows are inspected at a distance of approximately 450mm in
front of a white and black background under fluorescent tube lighting.
The robust nature of the filter window combined with our Quality
Assurance programme, reduces to an absolute minimum any wastage
from damage and so saves on cost.
