UV transmittance glass
UV & Near IR cut high contrast lens
UV ray reduces transmittance rate of glasses known as solarization.
Our newly developed glass has negative solarization effect which imporves transmittance rate without having glass deterioration by UV. This PUV glass is the most suitable for such optical equipments as lens for Blue-ray Disk, cover glass for sterilization lamp and so on which use UV ranging from 360nm - 450 nm.
