Mount the convex lens in holder in central upright and keep it in the middle of the optical bench.
Mount the card-board screen on another upright and keep it at distance equal to rough focal length of the lens, from the central upright.
Mount the burning candle in third upright and keep it on the other side of the central upright and near the end of the optical bench.
Adjust heights so that the inverted image of erect flame of burning candle is formed on screen. Move the screen to make the image sharp. The screen will be nearly at the focus of the convex lens.
