Abstract:
A lens assembly including a lens; a light absorber that does not transmit light with wavelengths from greater than or equal to about 250 nm to less than or equal to about 400 nm; a lens holder; and an adhesive configure to adhere the lens to the lens holder. The light absorber is positioned such that light having a wavelength from greater than or equal to about 190 nm to less than or equal to about 500 nm is not incident to the adhesive. A method including applying a light absorber, which does not transmit light with wavelengths from greater than or equal to about 190 nm to less than or equal to about 500 nm, to a lens; and configuring the light absorber and the adhesive so that the absorbed light is not incident to the adhesive.
