The 2010 International Optical Design Conference (IODC) was held June 13-17, 2010 in Jackson Hole, Wy. It was co-sponsored by OSA and SPIE. The IODC conference chairs were Julie Bentley, Anurag Gupta & Richard N. Youngworth.
The IODC traditionally includes one or more lens design and illumination design problems for members of the optical design community to consider.
The lens design problem was titled The Green Lens. The “green” movement is all about conserving resources. When designing and manufacturing a lens, one way to minimize needed fabrication resources is to need only one testplate pair (positive and negative) plus an optical flat, and need only one type of optical glass. The problem was to design a lens whose non-flat surfaces all share the same radius value, positive or negative, concave or convex.
The illumination design problem asked for the transfer of the maximum monochromatic flux from a 1-mm-square Lambertian source in air to an equal-etendue nonimmersed target. The target surface is rectangular with a 16:9 aspect ratio. The surface area of the target must be at least 4 mm². The target is defined such that only rays incident on the target surface at angles of θmax or less, relative to the surface normal, are considered to be within the phase space of the target, where the value of θmax is determined by the equal-étendue requirement.
