Gradient Index Properties

6.Add Fluorescence emission waveband edges and enter the number of wavelengths (# Inc) within each band. Emission rays will be generated at each wavelength. You can easily exclude the zero-to-first-wavelength band and last-wavelength-to-infinity band by entering 0 for the # Inc value.

7.Click Apply to apply the changes.

8.Check to be sure that the new property is clearly visible in the system tree.

Fluorescent properties are used in combination with the object’s bulk material properties. The Refractive Index and Absorption will be determined by the Material Property applied to the object. See “Applying Material Properties” on page 4.4.

Gradient Index Properties Standard Expert

Gradient Index Properties apply to materials with an inhomogeneous index of refraction. Examples are glass in which the index changes from center to edge, or optical fiber that also refracts light differently from center to edge.

The gradient index is coupled to the object's material property to vary the index of refraction along a parametric profile.

Note: GRADIUM, one of the types in the Type dropdown box, must be treated differently. Unlike others, the GRADIUM Gradient Index includes material property data and does not require association with a material property. In cases like this one, Do NOT apply a material property to an object that has GRADIUM applied.

For all other Gradient Index properties, you must apply a material property to supply the base index of refraction. For example, an Axial-Radial profile as shown in Figure 4.7 can be defined by doing the following:

Select Define|Apply Properties|Material tab and apply a glass material to the rod (e.g. Schott BK7).

Select Define|Apply Properties|Gradient Index property tab to apply the property. The profile is applied to the glass rod object along with an origin and propagation direction. An Up Vector is included to define lateral symmetries. Once this data is applied, the origin and direction vectors are updated if you move or rotate the object.
