A window assembly for installation across at least a portion of an opening through a partition frame. The window assembly includes a sheet of light-transmitting material defining opposite edges. Side members are disposed on the opposite side edges, and telescope relative to one another. At least one of the side members includes a connector for securing the window assembly to the partition frame. The connector engages the partition frame upon telescoping of the side members to secure the window to the partition frame.
