Summaries from Photonics West 2014


Bio systems

I presented a paper on the technology of insulating windows at Photonics
West in Feb. SPIE Newsroom asked for a short summary.
Identifying the best insulating windows
The final paper will be published  as
M. Watts,
Design strategy for low emissivity windows with effective
insulation, Proc. SPIE 8981, p. 8981-53, 2014. (In press.)

Impattern Solutions is an independent consulting company with a mission
to help you identify where and how imprint can be a cost effective solution
to your needs.

All the steps that are needed to deliver a patterned layer are represented
in  the Imprint Cell illustrated right. The requirements of each application
drive the process design of all the steps in the Imprint Cell
. The Imprint
step uses a Mold, an Imprint Material, and an Imprint Tool in combination.
