* Laser cut acrylic panels have been used to redirect sunlight into a [[light tube#Light tube with reflective material|light pipe]] or tubular skylight and, from there, to spread it into a room.<ref>Yeang, Ken.

* Attenuation being quite strong for distances over one meter (more than 90% intensity loss for a 3000&nbsp;K source),<ref>{{cite journal |doi=10.1582/LEUKOS.01.04.003 |first1=Victor |last1=Gerchikov |first2=Michele |last2=Mossman |first3=Lorne |last3=Whitehead |year=2005 |title=Modeling Attenuation versus Length in Practical Light Guides |journal=LEUKOS |volume=1 |issue=4 |pages=47–59 |s2cid=220306943}}</ref> acrylic broadband light guides are then dedicated mostly to decorative uses.
* Pairs of acrylic sheets with a layer of microreplicated prisms between the sheets can have reflective and refractive properties that let them redirect part of incoming sunlight in dependence on its [[angle of incidence (optics)|angle of incidence]]. Such panels act as miniature [[architectural light shelf|light shelves]]. Such panels have been commercialized for purposes of [[Daylighting (architecture)|daylighting]], to be used as a [[window]] or a [[canopy (building)|canopy]] such that sunlight descending from the sky is directed to the ceiling or into the room rather than to the floor. This can lead to a higher illumination of the back part of a room, in particular when combined with a white ceiling, while having a slight impact on the view to the outside compared to normal glazing.<ref>[http://www.bendinglight.co.uk/assets/pdf_downloads/How_Serraglaze_Works.pdf How Serraglaze works] {{webarchive|url=https://web.archive.org/web/20090305001319/http://www.bendinglight.co.uk/assets/pdf_downloads/How_Serraglaze_Works.pdf |date=2009-03-05}}.
