PLEXIGLAS® light transmission: More transparent than glass

© istockphoto / BlackJack3D

The light transmission of a material indicates how well it transmits incident light. Light transmission is, therefore, the technical term for transparency to light. Light-transmitting materials may be transparent or translucent: When viewed through transparent materials, contours are sharply defined; in translucent materials they are indistinct.

PLEXIGLAS® is available in both transparent and translucent variants, each of which allows a different degree of light transmission, or transmittance. This depends on the material type and the thickness of the sheet. Detailed information on the transmittance of individual PLEXIGLAS® variants is available in the corresponding Technical Information brochures.

Clear-transparent PLEXIGLAS® products show the highest transmittance, of up to 92 percent, in the visible range. The reduction is due only to a physical reflection loss of 4 percent at each of the light entry and exit surfaces; the material itself allows light to pass through unhindered. PLEXIGLAS® is thus one of the most transparent materials known, with almost no absorption of visible light in the material.

 

The best view

The thicker the sheet the more important the light transmission of a material. Large aquariums, for example, are constructed using transparent PLEXIGLAS® blocks with a thickness of several centimeters. Due to the unusually high light transmission of the branded acrylic, the fish can nonetheless be observed without a green cast or opacity and as they really are: in the right colors and proportions.
In greenhouses as well, plants and their gardeners benefit from the high light transmission of PLEXIGLAS®.

PLEXIGLAS® has outstanding fire properties, which are retained throughout the entire lifetime of the material.

Enjoy all weathers with a PLEXIGLAS® patio roof

For many, a patio is a second living room where family and friends can dine, relax and party. When it’s raining or the sun is burning down strongly, however, the patio can quickly become an unpleasant place.
