Abstract
An optical element comprising a plurality of transparent layers comprising one or more passive layers (11) and one or more active layers (12) wherein said passive layers (11) facilitate the transmission of electromagnetic radiation in a substantially unaltered form and the at least one active layers (12) include an active material dispersed through the active layer and having the capacity to intercept electromagnetic radiation of at least one predetermined wavelength or range of wavelengths and redirect at least a portion of energy of the intercepted radiation into the interior of the optical element, said layers being in face to face relationship and being optically coupled to each other.
Claims20
An optical element including outer layers enclosing at least one optically active inner layer selected to absorb incident near infrared radiation passing through the interface with one or more of said outer layers and fluoresce at one or more characteristic near infrared wavelengths without substantial heating, the respective layers being substantially transparent to both said one or more characteristic near infrared wavelengths and the visible spectrum, the outer and inner layers having relative refractive indices selected whereby said inner layer provides a light guide directing a portion of said fluorescence to an edge thereof.
An optical element as claimed at any one of the preceding claims and including one said inner layer.
