Understanding What Can Be Exported from Ansys Zemax OpticStudio

Geometries

In Ansys Zemax OpticStudio you need to define the geometries that will compose the optical system.

Two types of geometries can be used to define a lens in Speos:

Sequential geometry: corresponds to an assembly of surfaces.
Non-sequential geometry: corresponds to an object.

Table 1. Geometries with rotational symmetry
Sequential Geometries		Non-Sequential Geometries
Even asphere Extended asphere Q-type asphere Standard Extended Odd Asphere Odd asphere STOP	Standard surfaces	Annulus Even asphere lens Extended asphere lens Extended odd asphere lens Odd asphere lens Q-Type asphere lens surface Standard lens	Standard lenses
	Standard, Even Asphere and Extended Asphere surfaces		Standard lenses, Even Asphere lens, Compound lenses made of Asphere surfaces
	Standard, Q-Type Asphere surfaces		Standard lenses, Compound lenses made of Q-Type Asphere surfaces

	Standard and Biconic surfaces		Biconic lens
	Standard and Biconic Zernike surfaces		Compound lenses made of Biconic Zernike and Standard surface
	Zernike Standard Sag and Even Asphere surface		Compound lenses made of Zernike and Aspheric surface

Optical Properties

In Ansys Zemax OpticStudio you need to define the optical properties to be associated to the lenses of the optical system.

Important: The materials and coatings defined in Ansys Zemax OpticStudio are the optical properties considered in the Speos simulation and cannot be overridden by the Volume and Surface Optical Properties (VOP and SOP) defined in Speos.

Material

The Material corresponds to the Volume Optical Properties of the lens. Ansys Zemax OpticStudio provides an open catalog of glasses and their reference.

The following material information are exported in the *.odx file. After the *.odx file import in Speos, some information are displayed or not in the Speos Object information of the Optical Design Exchange feature:

The catalog used and the glass reference. Displayed in Speos.
The dispersion formula used. Not displayed in Speos.
The related coefficients. Not displayed in Speos.
The minimum and maximum wavelengths. Displayed in Speos.
The spectral absorption. Not displayed in Speos.
Ansys Zemax OpticStudio defines the spectral transmission. During the *.odx import, Speos deduces the spectral absorption.

Coating

The Coating corresponds to the Surface Optical Properties of the lens.

The reflection and transmission as a function of incident angle and wavelength are exported in the *.odx file.

Important: Coating data depend on the materials that define the diopter.

Sensors

In Ansys Zemax OpticStudio you need to define the sensors that will compose the optical system.

In case of sequential component, the sensors are defined using the size of an image surface.

In case of non-sequential component, the sensors are defined using the size and number of pixels of any Detector Rectange object.
