1. Syntec Technologies: Pushing the Polymer Envelope HRDT™ and patent-pending High Refraction Diamond Turning are trademarks of Syntec Technologies

2. 2 Smaller, lighter packaging Lower cost Higher quality Wider range of optical spectrums (IR and UV) Stronger environmental resistance Applications are Driving Innovation

3. 3 Keys to “Pushing the Envelope” Tolerances and costs established relative to need (proof-of-concept, prototype, low to high volume production) Designed to integrate into an assembly that meets all environmental constraints, not just size and weight, the inherent polymer advantages Highly repeatable; easily updated Wide range of materials with suitable optics properties Sophisticated manufacturing processes Withstanding extreme temperatures and chemical exposure is often critical, as are easy clean-up and resistance to damage

4. 4 Material Trends: Accelerating Since 1990 Higher flow rates Better component design Post processing Improved optics overall Common polymers available in optical grades Temperature ranges (below 0c to over 200c) Transmission quality (390 to 1600 + nm) Stability of index of refraction generally increasing More ways to manage birefringence

5. 5 Manufacturing Trends: Improving and Converging Extremely precise optical mold inserts –All geometries –Fully compensate for shrinkage Fast turnaround prototypes –No molds –Replicate production approach Finished optics, select polymers MoldingSingle Point Diamond Turning Shorter lead time for molds –Average 6 to 8 weeks –As little as 2 to 4 weeks –Unitized designs Shorter processing times –More capable machines –Better technician controls Finished optics, all polymers

6. 6 HRDT™ Processing Breakthrough Consequence: Many applications not feasible (time and/or $) Virtually all low volume ones Most high volume innovations Some high volume proven ones Hypothesis: Issue is a relievable surface energy problem Relieve material by annealing before diamond turning Customize amount of annealing plus machine settings, using repeatable formulas based on component geometry Problem: Surface failures on PEI and PES make SPDT unusable

7. 7 HRDT™ Results Typical SPDT machining; 390 Å achieved HRDT™ success; 60 Å achieved Optically unacceptable Fully repeatable and optically acceptable

9. 9 HRDT: Applications That Fit High heat, high index of refraction (e.g., datacom evanescent coupling) Innovation ideas where R & D funds are tight or short lead times vital Generally proven design and packaging, but inherently low volume Newer designs and packaging, either high or unknown volumes Optics that can be mounted to a PC board before wave reflow

10. 10 Key Questions Is overall application well under- stood or innovative? Optimizing new functionality or interfaces takes more cycles Are optical components low or high complexity? What is the value of each week of development time saved? How many proof-of-concept and prototype cycles make sense? More changes earlier increases product quality at lower risk & cost
