William Optics

Corporate
In a relatively short time, William Optics has established itself and its products as one of the world leaders in short-tube, highly-portable refractors, and has achieved quality recognition for many accessories such as the well celebrated WO Diagonals.

We plan to keep producing fine instruments both for the entry-level and the top-end segments. In the coming year, you will have many pleasant surprises: on top of a whole new range of larger Apochromatic telescopes, we will begin marketing new accessories and binoculars for all pockets.
