Excimer Laser Focusing Lens / 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 idealfor 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.
