Average transmittance in visible spectrum (400 – 700nm) >90%, as measured using 3mm
thick Optical Grade PMMA.
Please note that flow lines and weld lines on the external surfaces of the lenses are acceptable
if the optical performance of the lens is within the specification described in the section
“OPTICAL CHARACTERISTICS”
IMPORTANT NOTE – Lenses handling and cleaning:
Handling: Always use gloves to handle lenses and/or handle the lenses only by the flange.
Never touch the outside surfaces of the lenses with fingers; finger oils and contamination will
absorb or refract light.
Cleaning: Clean lenses only if necessary. Use only soap and water to clean the surfaces
and lenses. Never expose the lenses to alcohol, as it will damage the plastic.
