Photo Nanoimprint Lithography (P-NIL) promises to be a rapid and low cost methodology for manufacturing optical, electronic and optoelectronic micro-scale and nano-scale devices. One obstacle for the methodology is the high cost of molds or masters that will have a finite lifetime in terms of multiple copies. The work-around for this cost is to use Read More…

ACW High Refractive Index Materials for Nano-Imprint Lithography for AR/VR/MR
High refractive index (RI) materials are employed for production of quality diffractive optical elements (DOE) used in augmented, virtual, and mixed reality (AR/VR/MR) devices and a variety of optical sensors. Higher RI DOEs provide wider fields of view (FOV), and low-cost mass production of DOEs with RIs greater than 1.7 can be accomplished using photo Read More…
Very High Refractive Index Resins for P-NIL Applications
ACW introduces a new line of LuxNIL® very high RI resins for P-NIL VR/AR/MR applications or other thin coatings. These resins are hybrid organic/inorganic, low viscosity formulations containing PGMEA. They are suitable for spin coating, gravure coating, or ink-jetting to give thicknesses of 100 nm to 3 microns after evaporation of the PGMEA. The cured Read More…
Adhesives that block Visible and Near IR light
Do you want a UV-cure adhesive that blocks visible or Near IR light? At first thought, that might seem to be a paradox, but ACW has found a way to do just that. A1867-TX and A1867-TX2 are sister adhesives with different thixotropic indices. These are dual-cure (UV or heat) epoxy adhesives that will cure with Read More…
Adhesives that Survive Solder Reflow
Those working with semiconductors are familiar with solder reflow conditions. A PCB containing solder and flux is heated to ca. 150 °C (pre-heat), held there for 1-2 minutes (soak), heated to ca. 260 °C, then cooled. As devices are miniaturized, physical clamps holding and aligning components are increasingly replaced with adhesives. But solder reflow conditions Read More…
Addison Clear Wave Has Updated Its Photo Nanoimprint Lithography (P-NIL) Resins Brochures
ACW has updated its brochures for resins for P-NIL applications. The updated brochures include the results of environmental and thermal shock stress tests on resins coated on glass. The environmental stress tests were 1000 hours at 85 °C and 85% relative humidity. The thermal shock tests were 1000 cycles of 150 °C for 30 minutes Read More…
High Refractive Index (RI) Resins for Bright Diffractive Optical Elements (DOE)
High refractive index (RI) materials are used for diffractive optical elements (DOEs) employed in augmented, virtual, and mixed reality (AR/VR/MR) devices and optical sensors. One cost-effective approach for DOEs with high RI is to use a resin that can be processed rapidly by photo nano-imprint lithography (P-NIL) methods. When the RI exceeds 1.7 at 589 Read More…
Non-Yellowing P-NIL Resin for Diffractive Optical Element (DOE)
Photo nanoimprint lithography (P-NIL) processes are cost effective methods for production of diffractive optical elements (DOE) used in holographic displays. A limiting factor for this method is the environmental stability of the P-NIL resin. If the P-NIL material yellows considerably with aging, the DOE with have limited utility. In automotive applications, for example, the DOE Read More…
