Each chapter is a great introduction for a specific optics subspecialties. To do so, select LIGHTFORGE_GRIDXYZ from the macro list and you will be prompted for a location to save the file, after which the macro will produce a file called LightForge_gridXYZ.dat at the target location.The Handbook of Optics, from the Optical Society of America, is a tremendously valuable resource for all optics practitioners. The system is now ready to be sampled using the Lightforge_GridXYZ macro. Here is presented a simple example system showing the setup required when using the macro to sample a lens surface in ZEMAX.Ī Standard Lens object is created with a radius of curvature of 500mm and a radial dimension of 7.5mm, centred in x and y and with a z-position of 0.005mm:Ī Standard Lens object with a Rectangle object acting as a dummy surface (shown in red)Īs mentioned before, the macro will not produce a correct result when the sampling ray does not intersect with a surface, so a dummy surface is made by creating a Rectangle object with X and Y half widths of 7.5mm and a z-position of 0.05mm: The surface can be placed at other locations, including the z position of the lens, but a Boolean object must be constructed in order to create a window for the sampling ray to intersect the desired surface. The simplest way to do this is by adding a rectangle object with X and Y Half Widths of 7.5mm, and located +50um in z from your front surface (this ensures that manufacturing rules are adhered to). The entire 15x15mm area sampled by the macro needs to be fully specified so, for example, a radial optic must also be partnered with a square dummy surface in order for the sampling ray to intersect a surface in the corners of the sampling region. Full x and y dimensions smaller than or equal to 15mm.Must be the first surface intersected by a ray if the ray is object 1.The surface to be sampled must have the following parameters.

The ZEMAX system must be set up to provide an accurate representation of the desired surface with the range sampled by the macro. Lens units of the system should be set to millimetres in the General window under the Units tab. You should now see LIGHTFORGE_GRIDXYZ in your macro list

If ZEMAX was opened when the macro was copied, open the Macros drop down menu and select “Refresh Macro List”.

Copy the LightForge_GridXYZ.zpl file to the folder located at Root Drive:\Users\Your User Name Here\Documents\ZEMAX\Macros.

The macro must first be installed on the system: This data is simultaneously written to an external file in a user-selected folder location and then converted to ANSI format for upload to the LightForge website. The LightForge_GridXYZ macro works by creating a source ray, which is then moved in a raster scan pattern over a defined xy range while measuring the z-intercept of the first surface intersected in the ZEMAX system.
