International Optical Design Conference 2021.
For the 5th time, the International Optical Design Conference (IODC) included an Illumination Design contest. This year, the contest involved designing the optics to reverse a magical curse that was placed on Prince Lambert. The goal of the problem w

In illumination optics, color mixing is a key design task, but the realization can be a challenge. While tunable light sources based on multiple LEDs are commonplace, color homogenization is just as important for white LEDs, due to their spatial and

Optical Design and Fabrication 2019 (Freeform, OFT).
An all-reflective electronic viewfinder was designed using tilted freeform surfaces in a fully unobscured package. Tight distortion and telecentricity requirements moved the design from a two-mirror solution to a five-mirror solution.

Presented is a quasi-analytic method for irradiance evaluation through a single refractive surface from a single Lambertian source. The method is compared to Monte-Carlo raytracing for a sample system, producing in much less time an irradiance distri

Refractive eyepiece design forms are often limited by chromatic aberrations and require a mix of glass types to achieve sufficient correction, thus they are not conducive to manufacture in volume. Reflective surfaces are inherently achromatic and can

‘External quantum efficiency’, that is, the number of photons generated per electron passing through the p-n junction of an LED is probably the most important number to quantify the performance of an LED chip. Although advances in epitaxy have in

A method for 3D irradiance tailoring is introduced for extended sources, solving the flux conservation integral equation for the required freeform surface parameters; first by converting it into a nonlinear equation system, and then using standard nu
