Fresnel reflections in inverse freeform lens design
A. H. van Roosmalen, M. J. H. Anthonissen, W. L. IJzerman +1
In this paper we propose a method to design a freeform lens including the effect of Fresnel reflections on the transmitted intensity. This method is elaborated for a lens with one…
Modelling Surface Light Scattering in the Context of Freeform Optical Design
Vì C. E. Kronberg, Martijn J. H. Anthonissen, Jan H. M. ten Thije Boonkkamp +1
We present a novel approach of modelling surface light scattering in the context of freeform optical design. The model relies on energy conservation and optimal transport theory. F…
Design of a freeform two-reflector system to collimate and shape a point source distribution
A. H. van Roosmalen, M. J. H. Anthonissen, W. L. IJzerman +1
In this paper we propose a method to compute a freeform reflector system for collimating and shaping a beam from a point source. We construct these reflectors such that the radiant…
Systematic design of the color point of a white LED
Maryna L. Meretska, Gilles Vissenberg, Ad Lagendijk +2
Lighting is a crucial technology that is used every day. The introduction of the white light emitting diode (LED) that consists of a blue LED combined with a phosphor layer, greatl…
