This example demonstrates the use of image synthesis und animation of elements. A simple prism spectrograph is made up of 2 lenses and a dispersion prism. Fig. 3-1 shows the 2D view of the design, Fig 3-2 an 3D view. A bundle of beams is drawn for 546 nm. The two lenses project the object plane onto the image plane (1:1).

Fig 3-2: Spot diagram prism spectrograph (False colors)

The spot diagram (Fig. 3-3) of the image plane shows several spots corresponding to the wavelengths 450 nm, 500 nm, 550 nm, 600 nm , 650 nm, and 700 nm. Colors are false colors, deep blue belongs to the shortest wavelength defined for the particular optical system. Due to the dispersion several spots are visible. Note the variation in spot size caused by chromatic aberration.

See also how the angle of minimum deviation can be easily demonstrated by VOB++ using the animation feature: Spectrograph 1.
