Addison Clear Wave’s PFAS-free Epoxy Working Stamp Resins

Addison Clear Wave has released two new PFAS-free epoxy working stamp resins for UV lens molding and similar applications.  Working stamps can be cast on glass backplanes from metal master molds using a conventional anti-stick material.  The working stamps thus made have high water contact angles and can be used with standard imprint resins without Read More…

UV-NIL for augmented reality / virtual reality / mixed reality (AR/VR/MR) waveguides

In collaborative work, Addison Clear Wave and EV Group demonstrated commercially viable UV-NIL manufacturing processes.  SmartNIL® processing of LuxNIL® resins gave the following results. Refractive Index:  1.82 – 1.96 at 633 nm Resolution:  50 nm Height Gain:  0.64 – 0.80 nm average for 25 imprints Download the jointly issued Whitepaper for details of the process Read More…

High Resolution, High Refractive Index Nano-Imprint Lithography with Sub-nm Height Gain

ACW teamed up with EV Group to demonstrate a new standard of performance for wafer-level high RI UV nano-imprint lithography (UV-NIL) for augmented/virtual/mixed reality applications. Using EV Group’s SmartNIL® process and ACW’s high RI LuxNIL® resins, the team achieved 50 nm resolution imprints with RI as high as 1.96 at 633 nm and sub-nm average Read More…
