Title:
ULTRAVIOLET LED OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2022/075048
Kind Code:
A1
Abstract:
Provided is an ultraviolet LED optical member that has high transmittance in an ultraviolet range, and that is stable even during long-term use and has excellent reliability. This ultraviolet LED optical member exhibits, by having an optical member made of an organic resin, optical characteristics in which the average transmittance at a wavelength of 200-300 nm is 50% or more. Said optical member for this ultraviolet LED optical member preferably exhibits optical characteristics in which the transmittance at at least a wavelength of 200-250 nm is at least 60%.
