Sources

Only Sources in Sequential mode can be exported to the *.ODX file. Sources in Sequential mode are defined by Fields, OBJECT distance, ray aiming, and the STOP surface. Thanks to these elements you can represent an elliptical sources or point sources in Ansys Zemax OpticStudio. Both types of sources are imported as Surface source in Speos with an elliptical shape geometry on which the Surface source will be applied.

Elliptical Source

With an elliptical source, rays are emitted in a collimated beam (OBJECT emitting positioned at an infinite distance). That means the rays are emitted from an OBJECT represented by an elliptical surface where the z-axis of the source is determined by the chief ray.

Source InformationThe following source information are exported in the *.ODX file. After the *.ODX file import in Speos, information are displayed or not in a Surface source feature automatically created:


	Ansys Zemax OpticStudio	Speos
Source Type	Sequential source	Surface source
Intensity distribution	Parameter: Apodization type Value: Uniform / Gaussian / Cosine Cube	Parameter: Intensity Type Value: Lambertian (cos N = 1) Intensity will always be Lambertian
Spectrum	Parameter: Wavelength Value: list of wavelengths and weights	Parameter: Spectrum Type Value: Monochromatic if 1 wavelength defined Library if 2 or more wavelengths defined, along with corresponding spectrum file
Power/Flux	No power to be defined	Parameter: Flux Type Value: radiant flux of 1W
Exitance	Parameter: Output Exitance Value: False	Parameter: Variable exitance Value: False

Geometry Information:The following geometry information are exported in the *.odx file. After the *.odx file import in Speos, the geometry used to support the Speos surface source will appear in the SpaceClaim structure tree.


Ansys Zemax OpticStudio	Speos
Orientation	Intensity total angle = 0 deg to consider surface for collimated rays
Dimension: x and y half width
Position
Cone Half angle = 0 deg

Note: In Ansys Zemax OpticStudio, the X and Y dimensions of a collimated source can be asymmetrical. Upon import into Speos, the X and Y dimensions are made symmetrical using the larger value.

Point Source

With a point source, rays are emitted in a solid angle cone beam defined by half angle (OBJECT emitting positioned at a finite distance). That means the rays are emitted from an OBJECT represented by an elliptical surface where the z-axis of the source is determined by the chief ray.

Source Information:The following source information are exported in the *.ODX file. After the *.ODX file import in Speos, information are displayed or not in a Surface source feature automatically created.
