A new broad-band vacuum lens/window design is required for the new Atacama Large Millimeter/submillimeter Array (ALMA) band 2 receiver, intended to cover 67-116 GHz. A suitable anti-reflection coating (ARC) for this will be necessary. This paper presents the optimization of a candidate ARC designin ultra-high molecular weight polyethylene (UHMWPE), aswell as simulations and measurements of candidate designs insilicon. Machined triangular grooves are used as the ARC for the UHMWPE candidates, and stacked cuboids for the silicon candidate design.
