Understanding the Optical Design Exchange Parameters

The following page provides you with the list of the different parameters of an Optical Design Exchange feature.

Axis System

The Axis System of the Optical Design Exchange feature allows you to position and orientate the optical design system to be imported in the CAD scene.

The Axis System does not interfer with the imager and geometry positions inside the optical design system.

Global - Geometries

Geometries is an informational and read-only parameter in the interface that counts the number of geometries imported after computing the Optical Design Exchange feature.

Object/Surface

Objects and Surfaces are the reflection of what has been exported from Ansys Zemax OpticStudio. They provide information on the definition of each imported lens according to how they have been defined in Ansys Zemax OpticStudio.

Geometries indicate the type of object (lens or stop) and the corresponding line indexes from Ansys Zemax OpticStudio. Geometries indicate the type of object (lens or surface) and the corresponding line index from Ansys Zemax OpticStudio.

General Characteristics

  • Objects and Surfaces appear as children of the Optical Design Exchange feature node after computing the feature.
  • All displayed parameters are read-only.
  • All dimensions are expressed in millimeters.
  • Wavelengths are expressed in nanometers.
  • Infinite radius is expressed with a value of 0mm.
  • The order of the imported elements is respected between the SpaceClaim Structure tree, the Speos Simulation tree and the 3D view.

Object

Objects are represented with this icon . Each object correspond to a lens of the imported optical system.

As Speos element it includes:

  • Body dimensions
  • Back face and Front faces parameters
  • Back, Front and Edge faces Surface optical properties. Surface optical properties appear only when a coating is applied to at least one face.

  • Volume Optical Properties of the solid body

    Important: When defining sources and sensors in a simulation containing the imported optical design system, make sure to consider the spectral range of the Optical Design Exchange feature.
  • the link to the solid body in the SpaceClaim Structure tree. The Volume Optical Properties are applied to the body listed.

  • the list of the different faces composing each solid body face (Back Faces, Front Faces, Edge Faces).

    Each list is associated to an optical property. That means, the optical property is applied on all elements of a same list.

    Example: The Surface Optical Property name AR is applied on all faces of the Back Faces list.

Surface

Surfaces are represented with this icon . A surface correspond to an annulus/stop of the imported optical system.

The Annulus/Stop is the aperture in the system that limits the size of the beam transmitted through the system. The physical stop in the system usually joins the housing or other mechanical parts so that light cannot leak around the outside edge.

As Speos element it includes:

  • the body dimensions
  • the Surface Optical Properties definition of the face. It shows a no reflectance applied on the surface.
  • the link to the surface body in the Structure tree
  • the link to the face composing the body

Options

The Options correspond to specific settings of the Optical Design Exchange feature that are applied when running a simulation.

For more information on the Options, refer to Specific Simulation Options.
