optical properties
Light transmittance: Indicates the light transmittance of a sample with a thickness of 1 μm. Values include return loss.
Application example
nanoimprint
This is a processing technology in which a stamper with a nanoscale uneven pattern is pressed against a resin-coated substrate and then heated or light-cured to transfer the uneven pattern to the resin.
It is attracting attention as a next-generation mass production technology because it can be processed easily and at a low cost compared to conventional nanoscale processing technology.
This resin is a nanoimprint resin with a high refractive index, and can be applied to fabricate functional precision patterns with a high refractive index.
