High Transparence/High Weather Resistance Grade
HL-3000U Features
- High transparence, high weather resistance grade suitable for outdoors optical applications.
- HL-3000U cuts out UV light while showing high transmittance in the visible light range (400-700nm) equivalent to the HL-3000 lightguide plate grade.
Weather Resistance of HL-3000U
HL-3000U has better weatherability performance than HL-3000 and can reduce the deterioration of optical property (Yellowness Index, transmittance) when used outdoors.
