We present a compact two-lens high-density polyethylene (HDPE) $ f/1.6 $f/1.6 refractor design that is capable of supporting a 28-deg diffraction-limited field of view at 1-mm wavelengths and contrast it to a similar two-lens refractor using silicon lenses. We compare the optical properties of these two systems as predicted by both geometrical and physical optics. The presented analysis suggests that by relaxing telecentricity requirements, a plastic two-lens refractor system can be made to…

Designs for a large-aperture telescope to map the CMB 10× faster.
The new crossed Dragone telescope and receiver optics designs that increase the usable diffraction-limited field-of-view, and therefore the mapping speed, by an order of magnitude compared to the upcoming generation of large-aperture instruments are introduced.
Large-aperture wide-bandwidth antireflection-coated silicon lenses for millimeter wavelengths.
An AR coating for curved silicon optics comprised of subwavelength features cut into the lens surface with a custom three-axis silicon dicing saw is presented, and measurements of the optical properties of silicon at millimeter wavelengths at cryogenic and room temperatures are presented.

Ray-tracing and physical-optics analysis of the aperture efficiency in a radio telescope.
It is demonstrated that the Strehl ratio is equal to the phase efficiency when the apodization factor is taken into account and gives the designer/user of the telescope the opportunity to use the faster commercial ray-tracing software to optimize the design.
