Synopsys Inc.'s CODE V
10.3 adds support for new native aspheric surfaces and the Q-type aspheric
surfaces offer advantages over traditional polynomial-based aspheres for lens
design optimization and tolerancing. For example, the Q-type surfaces can be
more easily constrained during optimization to improve manufacturability and reduce
cost. In addition, CODE V's wavefront differential tolerancing feature supports
tolerancing on Q-type polynomial coefficients, which is for evaluating system
performance and manufacturability.
CODE V's enhanced surface
conversion capabilities make it easy to switch back and forth between the
Q-type formulations and traditional aspheric surface representations. This
allows designers to harness the power of the new formulations while maintaining
compatibility with established fabrication processes.
CODE V's Asphere Expert tool saves users
time by automatically finding optimal asphere locations in the lens system. The
tool uses an algorithm that takes into account both aspheric slope departure
limits and weighted constraints when computing recommended aspheric surface
locations. Users have the option to convert selected surfaces to aspheres and
optimize the resulting system for best final performance.
New built-in optimization
constraints in CODE V allow users to directly control the sag or slope
variations of Q-type aspheres to maintain manufacturability of the lens system.
For example, these constraints give users the ability to prevent the production
of designs where the sag of the aspheric parts is too large for interferometric
testing, and to ensure that designs do not require removal of an excessive
amount of material during polishing phases. In addition, a new macro function
allows aspheric surfaces to be evaluated and optimized for testability using
ZYGO's VeriFire Asphere interferometer metrology system.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
