Optical Lens Design, Native Gradient Index Support – reTORT 2.0.27 Released
Optical lens design made easy, with native, advanced gradient index and metasurface capability.
E x H, Inc. has just released reTORT 2.0.27, an advanced ray tracer enhanced by additional easy to use gradient index support features.
With reTORT, you will realize every benefit ever promised by transformation optics.

Enhanced Gradient Index Features
We provide one click, customizable GRIN definitions. Therefore, you can easily specify radial, axial, or spherical polynomial profiles. You can specify radial/axial polynomials with or without cross terms. We make your setup easy so you can move on to a solution. Then, optimize your design with the best geometric optics
solution available today.
Our arbitrary binary mixture engine is very well known. With our engine, you can allow reTORT to combine two dispersive materials to reach your goal. If you wish, you can also specify pure index of refraction GRIN models.
VERY IMPORTANT – Our very efficient sampling algorithms assure that binary mixture GRINs are manufacturable. You are assured that your design optimization remains within realistic bounds. Your design will use attainable indices of refraction. Therefore, never complete a design that is outside of the limits you yourself can set.
The features we offer in reTORT mean that you can design singlets that replace achromatic doublets.
We have the most flexible dispersive GRIN interfaces in the ray tracer market today. Many other solutions only model GRINs natively as non-dispersive, treating all wavelengths in the exact manner. In this way, you natively get color correction when using our reTORT ray tracer. That way, you don’t need to add external scripts and libraries to adjust your results.
Other Enhancements in the reTORT 2.0.27 release
We now offer full support for solved lens diameters. With this feature, each lens diameter is solved during your optimization. Therefore, pre-specified edges won’t get in the way of your reaching the optimal solution.
We natively optimize for lateral color correction. In reTORT, we consider lateral color correction in our core spot size and wavefront error computations.
Upcoming topics of common interest in optical lens design
There are two special topics we’d like to offer you in upcoming weeks. We think you’ll find these very interesting:
- You deserve a more complex SWaP reduction case. This type of use case can show the power of reTORT in optical lens design. The ease with which you can substitute two or three lenses with an achromat singlet is a powerful weapon to add to your quiver.
- The native capability of reTORT to accurately optimize dispersive GRINs is a powerful area to explore in optical lens design. Dispersive GRINs with aspheric lenses are a very powerful area of lens design Our arbitrary binary material mixture engine gives you tremendous flexibility in design.
