High Refractive Index Polymers for Optical Applications
WebHighRI’s high refractive index materials can be used for numerous applications to meet the existing fabrication process requirements and discover new opportunities. Numerous Applications Are possible: UV and Thermal Nanoimprint Lithography with controllable residual layer High Resolution (sub-10 nm) Nanoimprinting Patterning with Photoresist WebFeb 16, 2011 · The refractive index rose rapidly for gaps below about 5 µm, and the aluminium material, with its tiny gaps, had the highest maximum index. The researchers also made thicker versions of their metamaterial, generating up to five layers of the gold pattern. A high refractive index material will generally have a small Abbe number, or a high optical dispersion. A low birefringence has been required along with a high refractive index for many applications. It can be achieved by using different functional groups in the initial monomer to make the HRIP. See more A high-refractive-index polymer (HRIP) is a polymer that has a refractive index greater than 1.50. Such materials are required for anti-reflective coating and photonic devices such as See more The synthesis route depends on the HRIP type. The Michael polyaddition is used for a polyimide because it can be carried out at room temperature and can used for step-growth polymerization. This synthesis was first succeeded with polyimidothiethers, … See more • Refractive index • Refractometer • Abbe number • Optoelectronics See more Refractive index A typical polymer has a refractive index of 1.30–1.70, but a higher refractive index is often required for specific applications. The refractive index is related to the molar refractivity, structure and weight of the monomer. In … See more High refractive indices have been achieved either by introducing substituents with high molar refractions (intrinsic HRIPs) or by combining high-n … See more Image sensors A microlens array is a key component of optoelectronics, optical communications, CMOS See more • Ralf B.
