What is non-sequential ray tracing?
Non-sequential ray tracing implies that there is no predefined sequence of surfaces which rays that are being traced must hit. The objects that the rays hit are determined solely by the physical positions and properties of the objects as well as the directions of the rays.
How do you convert sequential to non-sequential zemax?
Using the Convert to NSC Tool Select Convert to NSC Group from the File tab. The Convert to NSC Group tool will automatically convert sequential surfaces to their equivalent non-sequential objects.
What is sequential ray tracing?
Sequential ray-tracing Ray-tracing involves modelling the geometrical components of optical systems, defining the optical properties of these objects, approximating light sources with directional rays and then predicting real-world system behaviour by propagating these rays through system models and by observing.
How long does it take to learn zemax?
It depends on the Learning Plan. For Optical System Design for example, we recommend you take 5 full days. Trainees are free to break it down as they wish to fit their schedule within the duration. Each individual course is designed be about half a day to go through.
How much does zemax cost?
It offers a variety of simulations, along with concurrent opto-mechanical design. OpticStudio: OpticStudio from Zemax is priced between $4,900 and $14,900 depending on its edition. One year of maintenance is included, but fees are tacked on after that.
Is zemax free for students?
If you are a university student enrolled in an optics course you can apply for free use of OpticStudio through the Zemax Global Academic Program.
What can zemax do?
It works by ray tracing—modelling the propagation of rays through an optical system. It can model the effect of optical elements such as simple lenses, aspheric lenses, gradient-index lenses, mirrors, and diffractive optical elements, and can produce standard analysis diagrams such as spot diagrams and ray-fan plots.
Is zemax software free?
Zemax is committed to providing free optical design software and online technical resources to prepare students and educators for a successful career in optics.

When to use sequential or non-sequential mode?
The Sequential Mode is mainly used for designing imaging systems, while the Non-Sequential Mode is mainly used for illumination system design and stray light analysis. The key difference is that in Non-Sequential Mode, ray path is not specified by user in a strict sequence.
Is the NSCE the same as the sequential editor?
The Non-Sequential Component Editor (NSCE) still contains the same non-sequential components, corresponding to the lenses in sequential Cooke Triplet file. Open a layout to view the three lenses in the NSC Editor.
When to use non sequential mode in OpticStudio?
If you are working with a system that requires more flexibility, then you will want to use Non-Sequential Mode. Non-sequential ray tracing allows rays to propagate through optical components in any order and allows rays to be split, scattered, and reflected back to an object that they’ve already encountered.
Why are non sequential solution spaces discontinuous?
As mentioned previously, non-sequential solution space tends to be discontinuous due to the pixelated nature of detectors. If the energy in each ray is assigned to only one pixel, there is no quantitative difference when a system change causes the ray to shift anywhere within that pixel.
