Holographic cure monitoring of the DuPont Somos TM 7100 stereolithography resin

The optical characteristics of a commercial UV curable resin are investigated using non-degenerate four-wave mixing. The material assessed is an epoxy resin, DuPont Somos TM 7100. The holographic gratings were written at a wavelength of λ=351.1 nm for an irradiance range 0.5–3.0 W/cm 2 and read at λ...

Summary:The optical characteristics of a commercial UV curable resin are investigated using non-degenerate four-wave mixing. The material assessed is an epoxy resin, DuPont Somos TM 7100. The holographic gratings were written at a wavelength of λ=351.1 nm for an irradiance range 0.5–3.0 W/cm 2 and read at λ=632.8 nm in order to assess the reactivity, curing speed, shrinkage and resolution of the resin.
