Don’t miss these customer-led presentations at ENVISION USA 2018

We’re excited to reveal three more speaker sessions for ENVISION USA 2018, the Zemax conference taking place November 5-7 in Las Vegas. Zemax leaders will share what’s coming soon to make STOP analysis easier and more accurate and much more. You can view the full agenda here. Customers will present on a wide range of topics including the following three talks you don’t want to miss:

Gaussian beam calculations compatible with general astigmatism
Speaker: Paul Colbourne, Director, Optical Switching Technology Advanced Research, Lumentum

Most calculations of Gaussian beam properties, such as beam size and waist position, assume “simple astigmatism,” in which the beam and all cylinder lenses are aligned with the x-y axes, so if a system doesn’t meet this condition, the results re invalid. Even if an optical system does not have intentionally rotated elements, astigmatism caused by off-axis incidence on optical elements can create a state of “general astigmatism.” This causes calculations which assume simple astigmatism to give incorrect results. During this session, learn a new methodology that has been developed for calculating Gaussian beam properties using rays, which is compatible with general astigmatism, so you can achieve accurate results with no restrictions on the orientation of optical elements.

Incorporating commercial photographic lenses into your optical system designs
Speaker: Craig Unick, Senior Optical Designer, 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.

Optical design of a compact DUV spectrometer for entry, descent, and landing applications
Speaker: Waylin Wing, Optical Engineer, LumenFlow Corp.

Learn about the design of a compact deep ultraviolet (DUV) spectrometer which is a component of a recently awarded NASA grant, where the objective is to demonstrate feasibility of rugged and small spectrometers for DUV analysis of atmospheric properties during the entry, descent, and landing (EDL) phase of a mission for planetary landing craft.

Don’t miss your chance to join us in Las Vegas, November 5-7, 2018. Connect with peers, hear about more innovative solutions, and enjoy a hosted dinner reception.
