OPTICAL SCATTERER COMPRISING A SCATTERING PORTION FORMED FROM A FOAM COMPRISING AT LEAST ONE FLUOROPOLYMER
First Claim
1. An optical diffuser having a diffusing portion capable of being passed through by the luminous flux emitted by a point light source, when said optical diffuser is mounted on said point light source, wherein said diffusing portion is formed from a solid foam comprising at least one fluoropolymer, said fluoropolymer being a copolymer of vinylidene fluoride (VDF) with a fluorinated cornonomer selected from the group consisting of chlorotrifluoroethylene (CTFE), hexafluoropropylene (HFP), trifluoroethylene (VF3), tetrafluoroethylene (TFE) and mixtures thereof.
