Abstract: A freeform lens containing giant red and green quantum dots (QDs) was designed to be used for a direct-illumination-type LED backlight wide-color-gamut display. Encapsulating the QDs with the freeform lens enabled us to not only… read more here.

Abstract: Freeform lens design for the prescribed irradiance without thin element and paraxial approximations is very complicated. We propose to transport a point source irradiance before the required freeform lens into an intermediate irradiance estimate next… read more here.

DOI: 10.3390/app7111195
Abstract: In this paper, we used a freeform lens in a long-wave, un-cooled, refractive infrared (IR) thermal imager and present the design strategy and test results. This optical system is composed of only one freeform lens… read more here.
