Optical diffusers based on silicone emulsions

Intravital fluorescence imaging of mouse brain using implantable semiconductor devices and epi-illumination of biological tissue

“…Optical diffusers are broadly classified into two types: surfacerelief-type and volumetric type [32]. Surface-relief type optical diffusers can scatter light employing the microstructures on the surface [33,34], whereas volumetric-type optical diffusers can scatter light employing the scattering media [35,36]. From the stand-point of creating uniform illumination, it is noteworthy that our epi-illumination method utilizes biological tissues as a volumetric-type optical diffuser.…”

A novel optical diffuser based on polymer micro-balls-filled nematic liquid crystal composite film

“…Liquid crystal displays (LCDs) are widely applied in cell-phones, laptops and computers, and optical diffusers are essential constituents of LCDs that enable high performance light management with independent control of light distribution patterns. [1][2][3][4][5] Transmission and haze are two main indices used to characterize optical diffusers, and two broad types of optical diffusers in the LCDs are the top diffuser lm and the bottom diffuser lm. In general, the top diffuser lm requires high transmission and low haze, 6 while the bottom diffuser needs high transmission and high haze, which have been focused and investigated recently.…”

Optical diffusers with enhanced properties based on novel polysiloxane@CeO2@PMMA fillers

“…1 As is well known, the constituent materials of optical diffusers are polymer materials, such as polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), or polycarbonate (PC), 2-4 which have very good optical characteristics. 7 One of them is mainly dependent on the microstructures of the surface layer, such as microlenses, pyramids, rough surfaces and other microstructures, and is called surface-relief diffusers. 5,6 At present, there are two main types of diffusers that achieve good optical diffusion in LCD.…”
