Adhesive for optical member, optical element, and optical device

Abstract

An adhesive for optical components, an optical element, and an optical machine are disclosed. The adhesive for optical components comprises an alicyclic epoxy compound, an oxygen-containing heterocyclic butyl compound, a hindered amine light stabilizer, and an antioxidant. Regarding a 100 μm thick cured copy of the adhesive for optical components, prepared by irradiating it with light of wavelength 365 nm at an energy density of 3000 mJ / cm², the absolute value of the difference in refractive index before and after a high-temperature and high-humidity test in an environment of 65°C and 90%RH for 24 hours is less than 0.002.
