Deadline to register for ENVISION USA 2018 approaching quickly
ENVISION USA 2018 is just a few weeks away—but there’s still time to register and if you register two people at the same time, one conference pass is free! You’ll hear from leaders in optics who have developed breakthroughs, learn best practices and tips and tricks to get the most out of Zemax software, get the first look at our next wave of product development and give feedback to influence the future of Zemax. Plus, it’s a great opportunity to connect with your peers, share your story with the Zemax community, and enjoy getting to know more from an outstanding network.
If you haven’t seen our speaker lineup yet, take a moment to check out the full schedule of speakers from Zemax and our customers.
Three customer presentations you don’t want to miss:
Going the extra mile with Contrast Optimization: a practical comparison of micro-imaging system optimization
Bob Householder, Access Optics
With the introduction of the Contrast Optimization feature in 2017, imaging system designers have another option for targeting imaging quality. The new technique is not only an alternate to direct MTF optimization, speed and performance improvements are possible. The seminar will take a practical approach in the use of Contrast Optimization in the development of a micro imaging system as is commonly used in robotic surgery, general surgery and precision small-scale imaging in defense, industrial, and commercial markets. A comparison will be made using other optimization methods and also look at results using an alternate lens design program.
How to properly analyze designs that violate standard approximations for low-cost imaging applications
Jeremy Huddleston, LightPath Technologies
This session will review novel techniques and lessons learned for evaluating compact, low-cost IR imaging lenses. These lenses are particularly challenging to design due to stringent limitations on cost, size, available materials, and number of elements. As a consequence, the necessary performance trade-offs often lead to unexpected but significant inaccuracies for standard calculations of imaging design metrics, such as EFL, f/#, FOV, MTF, distortion, relative illumination, and even achromatic and athermal analysis. Design examples will be used for lenses currently on the market, including patent-published details of the original Lepton lens inside the successful FLIR ONE thermal imager for cell phones―a design that broke conventions and began the trend towards thermal imaging in consumer applications.
Incorporating commercial photographic lenses into your optical system designs
Craig Unick, Keo Scientific
Proof of concept experiments and home-made instruments have served a broad community of researchers well. In many cases, off-the-shelf lenses from Canon, Nikon, Fujinon, and others are used where a high-resolution flat image with accurate color registration is required. But, newer generations of instruments require better performance, which can only be achieved via thorough optical design. OpticStudio provides the framework to model these optical systems, but finding the information on the actual lens prescriptions can be challenging. During this session, you will learn the background on instrumentation designed using camera lenses and the patents of commercial photography lenses. The talk will culminate with an example of how to implement a lens prescription from a patent in OpticStudio, verifying that the performance of the lens prescription matches the real-life lens.
We hope to see you there!
