Sun Ray Photo Company made photographers' equipment including camera tripods and four photo enlargers. The tripods were multi-sectional, fabricated in chrome-plated steel tubing and brass friction fittings. The photo enlargers, three of which employed a double condenser, are the Arnold D, Mastercraft 23, and Mastercraft 43 models. The exception is the Aristocrat A, Sun Ray's initial entry, which is equipped with a diffusion head. The Aristocrat A is focused by means of a focusing tube. The other Sun Ray enlargers are focused through a bellows (photography). None of Sun Ray's enlargers are equipped with autofocus. All use a single post column. Aside from the corporation's final enlarger, the Mastercraft 43, each has a 2.25 × 3.25-inch format. Mastercraft 43 has a 4 × 5-inch format. The Arnold D enlarger model features a faster standard lens than any of the others.
