v2.1 of the reTORT Optical Ray Tracer released by E x H
v2.1 Create spot diagram wizard and lens stack
E x H, Inc. is very proud to announce release of v2.1 of its increasingly popular reTORT Ray Tracer. With the included GEMSIF computational framework, reTORT allows the speedy design of complex optical lens systems. Traditional symmetrical lenses are no problem. Also, arbitrary or freeform geometry is equally handled well by reTORT.
Our Customers Drive E x H Development
The reTORT Ray Tracer is the only ray tracer on the market to include native support for gradient index lenses and the addition of metasurfaces. reTORT allows optical lens design of highly complex homogeneous lens systems better and faster. reTORT provides the capability to use the newest technologies. Therefore, reTORT is key to further reduction of size and weight while at the same time increasing performance.
E x H is quickly leading the pack in making the power of geometrical and transformational optics available to everyone in optical lens design, university researcher and student.
E x H, Inc. is very proud of the source of suggestions for the improvements in v2.1. Almost all of the updates, improvements and added functionality came from focus groups with current reTORT licensees. E x H is working hard to provide Customers with the tools they need and will continue to follow a diligent Customer-focused and agile approach to development. Those of you already involved in optical lens design are best able to make needed suggestions to improve their workflow.
What Has Changed in v2.1
Some of the changes in v2.1 include:
• Use of Dummy and other Mid-Air Surfaces was not clear in our GUI. You can now use any number of Dummy surfaces. Dummy surfaces are easily entered and editable from the lens stack.
• Obtain results from any surface including dummy surfaces.
• Improved focal plane controls in our Wizards. Now, you can modify the focal plane location from any result Wizard. You do not need to close the Wizard and modifying it manually.
• Easier identification of surfaces in a lens stack by row number with consistent easy-to-use references in status, error messages and results.
• We’ve hidden the thickness of the last surface. In this way, it is not accidentally used in specifying the working distance.
• We added an Image Plane surface type. You can now specify the working distance to the focal plane in the lens stack editor.
• We fixed a bug that affected some mid-system results. In this way, you can easily obtain results at any point in the lens stack.
Please Note Changes in Resource Files
The scope of changes in v2.1 did affect some resource files we provide for training and quick start designs. These include:
- The SWaP reduction tutorial which provides a good intro to reTORT/GEMSIF basics
- The Slide Projector Lens GEMSIF file which provides a good exercise in local optimization
- The Tessar Lens GEMSIF file which provides a good intro to our unique global optimization technique
- The Telephoto Lens example GEMSIF file
- The Metasurface example GEMSIF file. This provides a good intro to use of ideal metasurfaces. In this way, this file is good for training in the design of lenses using metasurfaces Please don’t forget to then follow-up with our Real Metasurface capability which is more useful for manufacturable designs.

About E x H, Inc.
E x H’s mission is to provide you with advanced optical system simulation tools. The result is tools that allow you to design optical systems that are smaller, lighter and faster.
Some of our solvers are licensed from Penn State University. PSU is one of the leading research institutions in the USA.
We have participated on multiple programs funded by DARPA that have allowed us to develop software on the leading edge of technology. Outside of the optical space, this same reTORT Ray Tracer was used to fast prototype the transformational optics that proved the concept for Isotropic Systems’ high throughput, multi-beam satellite terminals (https://www.isotropicsystems.com/).
On the business side, we have been backed by Gran Sasso Ventures, the same venture capitalists that funded collaboration software firm Compoze Software, now a part of Oracle [ORCL:NYSE], and multitouch technology inventor FingerWorks, the driver of touch screen technology and now a part of Apple [AAPL:NASDAQ]. E x H is at the forefront of transformation optics.
