The picture below shows how to draw a ray diagram for an object that is nearer to the lens than F. Click here for a ray diagram for an object that is further away than F.

The bottom of the object is placed on the principle axis. Two rays of light are drawn from the top of the object. The first ray of light is parallel to the principle axis and therefore passes through the focal point. The second ray of light goes from the top of the object and passes straight through the centre of the lens.

Unlike the previous page, the rays are diverging (moving apart) on the right side of the lens. The eye looks back along the rays that seem to have come from a point behind the object where the two rays of light cross. This is where you draw the top of the image. The bottom of the image is still on the principle axis.

The image is called virtual because the light rays never really go there (compare this with a real image). The virtual light rays are drawn as dotted lines. The image is called upright because it is the right way up (compare this with an inverted image). The image is bigger than the object and on the same side of the lens as the object.

When the object is nearer to the lens than F (less than the focal length) a convex lens acts as a magnifying glass.

Moonleds are also committed to the Human Centric Lighting, includes natural sunlight, eye protection healthy spectrum, etc. Deep red 660nm and Near Infrared 850nm LED, two colors in one 3535 reliable package design, make the lighting design more compact, cost-saving, and much more convenient for installation.
