Abstract
Herein disclosed is an optoelectronic unit measuring device comprising an objective lens, an imaging lens, a photographing lens, and a focus adjustment module disposed in a first light path. The objective lens receives a first testing light and converts the first testing into a second testing light. The imaging lens receives the second testing light and converts the second testing light into a third testing light. The photographing lens receives the third testing light and measures beam characteristic. The focus adjustment module selectively provides a first light transmitting member in the first light path, and adjusts the third testing light to focus at a first focus position or a second focus position. Wherein the focus adjustment module comprises a first carrier plate having a first area with the first light transmitting member, and moves the first carrier plate to selectively align the first area with the first light path.
