Optical adhesives are transparent, low-outgassing formulations — typically UV-curable acrylates or optically clear epoxies — used to bond, pot or encapsulate optical elements such as lenses, prisms, waveguides and sensor windows in aerospace assemblies, offering controlled refractive index matching, high light transmittance and resistance to radiation, thermal cycling and humidity.
