What is Nanoprism??


TransmissionSimplest possible case Yellow source no losses 100 % transmissionRed source 20 % reflection 10% from each face 80 % transmission

Add a simple prismYellow source 20% losses 80 % transmissionRed source 100% transmission


How do we measure Nanoprism

transmission?

Output without panel Output with panel


Transmission % = Output with panel x 100

Output without panel

Nanoprism 89%

What is Nanoprism?


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.

Nanoprism


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
