Six Best Practices for Optical Product Design Teams
In their groundbreaking study Six Myths of Product Development, Stefan Thomke and Donald Reinertsen exposed common fallacies of product development and presented best practices for overcoming them (Harvard Business Review, May 2012). This eGuide highlights how Zemax Virtual Prototyping applies six of these best practices—and what it means for the optical products your team designs. Learn the value of:

Remaining open to an evolving development plan
Using iterative—not linear—design processes
Experimenting with smaller batches for faster feedback
Quantifying the cost of delays and factoring it into your decisions
Making information flows visible

Optically Rewritable LCD Could Enable Flexible Displays
As with conventional LCDs, the ORWLCD is structured like a sandwich, with a liquid crystal filling between two plates. However, unlike conventional LCDs, where electrical connections on the plates create the fields needed to switch pixels from light to dark, the plates of ORWLCDs are coated with molecules that realign in the presence of polarized light and switch the pixels.

Diffractive Optical Elements: Minimizing Zero Order
Recent advances in diffractive optical elements have made them a standard component in laser material processing, medical and aesthetic lasers, and structured light projection systems. Enhancements in DOE design and manufacturing processes have reduced undesired orders and minimized zero order while improving uniformity and achieving higher diffractive efficiencies.
