A microlens is a small lens, generally with a diameter less than a millimetre (mm) and often as small as 10 micrometres (Âµm). The small sizes of the lenses means that a simple design can give good optical quality but sometimes unwanted effects arise due to optical diffraction at the small features. A typical microlens may be a single element with one plane surface and one spherical convex surface to refract the light.

In the diagram, the equilibrium level of output and demand is determined where this desired spending curve intersects a line that represents the equality of total income and output (AD=Y). The intersection gives the equilibrium output, Y.n the Keynesian cross diagram (or 45-degree line diagram), a desired total spending (or aggregate expenditure, or  aggregate demand ) curve (shown in blue) is drawn as a rising line since consumers will have a larger demand with a rise in disposable income, which increases with total national output.
