How do we measure Nanoprism
transmission?
Output without panel Output with panel
Copyright SLP UK Ltd 2013
Transmission % = Output with panel x 100
Output without panel
Nanoprism 89%

50 % transmission Opal 70 % transmission Opal
The shape of the distribution is the same the only difference is amount of light transmitted.
Does the light from an opal sheet go in a useful direction ?
Nanoprism is not simply a diffuser

70 % transmission Opal Nanoprism
Nanoprism increases intensity to the working plane

From the graph above we can see that the limit for meeting 3000cd/m2 is 14200 Lumens per m2 input from the source. For a luminous area of 585 x585 mm this equates to 4800 Lumens input.

Not Just a Simple Diffuser
It’s An Optical Controller!! Nanoprism is efficient:
• As we have stable production transmission is at 89%. Practical measurement.
• Nanoprism increases useful flux delivery to the working plane
• You can use fewer or lower power luminaires to achieve the same illuminance specification.
• Nanoprism decreases intensity above 65°
• You can meet low luminance and cut off specifications, we can easily predict Nanoprism behaviour for any specification
