ETL - EDL - NEDL
These lenses are manufactured with a synthetic fused silica material and it has a high transmittance value in the ultra-violet wavelength of 180 − 400nm. They have excellent performance and are ideal for focusing and imaging applications. There is no adhesive or heat absorption material used to produce these lenses, as a result they show high resistance to the ultraviolet light.
