Syntec Technologies: Pushing the Polymer Envelope HRDT™ and patent-pending High Refraction Diamond Turning are trademarks of Syntec Technologies
Applications are Driving Innovation Wider range of optical spectrums (IR and UV) Lower cost Smaller, lighter packaging Stronger environmental resistance Higher quality
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 • Withstanding extreme temperatures and chemical exposure is often critical, as are easy clean-up and resistance to damage Sophisticated manufacturing processes
Material Trends: Accelerating Since 1990 Improved optics overall • Temperature ranges (below 0c to over 200c) • Transmission quality (390 to 1600 + nm) • Stability of index of refraction generally increasing Common polymers available in optical grades More ways to manage birefringence • Higher flow rates • Better component design • Post processing
Manufacturing Trends: Improving and Converging • 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 Molding Single Point Diamond Turning • Extremely precise optical mold inserts • All geometries • Fully compensate for shrinkage • Fast turnaround prototypes • No molds • Replicate production approach • Finished optics, select polymers
Consequence: Many applications not feasible (time and/or $) Hypothesis: Issue is a relievable surface energy problem • Virtually all low volume ones • Most high volume innovations • Some high volume proven ones • Relieve material by annealing before diamond turning • Customize amount of annealing plus machine settings, using repeatable formulas based on component geometry HRDT™ Processing Breakthrough Problem: Surface failures on PEI and PES make SPDT unusable
HRDT™ Results Typical SPDT machining; 390 Å achieved Optically unacceptable HRDT™ success; 60 Å achieved Fully repeatable and optically acceptable

HRDT: Applications That Fit Newer designs and packaging, either high or unknown volumes High heat, high index of refraction (e.g., datacom evanescent coupling) Optics that can be mounted to a PC board beforewave reflow Generally proven design and packaging, but inherently low volume Innovation ideas where R & D funds are tight or short lead times vital
Key Questions Are optical components low or high complexity? • Is overall application well under- stood or innovative? • Optimizing new functionality or interfaces takes more cycles • How many proof-of-concept andprototype cycles make sense? • More changes earlier increases product quality at lower risk & cost What is the value of each week of development time saved?
Key Assumptions Assumptions Low Optics Complexity High Optics Complexity Cost of first mold Savings for subsequent molds (both in time & $$) Cycle time to make mold (in weeks) HRDT weeks saved per cycle Development savings per week Beta Production Quantity Volume Production Quantity $12,000 10% 4 3 $10,000 0 1,000 $25,000 20% 8 7 $10,000 10 1,000
