MesoOptics

Philips Ledalite’s MesoOptics technology offers a revolutionary way to purify and control light–allowing for the creation of vision-friendly lighting solutions that are exceptionally energy efficient.

Overview

Like many scientific breakthroughs, MesoOptics was inspired by nature. Butterfly wings consist of three-dimensional crystal nanostructures which selectively curve and scatter light. MesoOptics replicates the same effect, using holographic technology.

MesoOptics is produced in a manner similar to the holographic microstructures that appear on most credit cards. Using patented processes, lighting distributions less than 5 microns in size are applied to a recyclable substrate, creating a highly efficient and unique lighting control approach.


Exceptional Control & Efficiency

MesoOptics technology provides the best possible combination of control and luminance. Higher transmission efficiencies than traditional optical and control methods mean lower energy consumption. Small amounts of controlled brightness are introduced to the vertical surfaces, creating a brighter and more visually comfortable environment without unwanted glare.

Recessed: Exceptional Control & Efficiency

MesoOptics technology allows recessed lighting to have the best possible combination of lighting control and brightness–with efficiencies that are almost 20% higher than traditional recessed products. In many cases, this can result in a typical space utilizing up to 35% less energy for lighting. A small amount of controlled brightness is introduced to the walls and ceiling, creating a brighter, more pleasant environment without causing unwanted glare.

 

 

 

Suspended: Excellent Results with Fewer Fixtures

MesoOptics technology can help achieve an incredibly low peak candela angle. As a result, suspended fixtures can be spaced up to 16' apart with a 6" drop and still achieve less than 9:1 ceiling uniformity. You can create a balanced luminous environment in any space with smooth gradients of light on the ceiling, fewer fixtures and less energy.

Sustain

MesoOptics’ highly efficient material allows up to 95% of the light to pass through, creating highly energy efficient lighting products.

 

FAQ

What are conventional diffusers?

There are two types of conventional transmissive diffusers: bulk (or volume) diffusers such as translucent plastic, and surface relief diffusers such as ground and etched glass. While conventional transmissive diffusers are often used in architectural luminaires, they suffer from two serious problems: 

  • Inefficient transmission – Typical diffusers such as opal and translucent white plastics allow between 30% and 65% of light to be transmitted through the material. The remainder of light is either reflected as backscatter or absorbed into the material. 
  • Lack of control – A good diffuser should completely obscure the light source when you look directly at it through the diffuser. Seen from any angle, the diffuser should exhibit a uniform surface luminance (or “photometric brightness”). In doing so however, conventional diffusers scatter light equally in all directions. They also exhibit severe backscatter. This makes it difficult to design luminaires with high luminaire efficiencies and sharp cutoff angles for glare control.

How are MesoOptics diffusers different?

Conventional diffusers are of limited use in high performance optical systems because of their low transmissive efficiency and poor optical control characteristics. By contrast, MesoOptics diffusers offer both high efficiency and the ability to create controlled beam patterns.


What are MesoOptics diffusers?

MesoOptics diffusers are created with tecchnologies capable of producing micro and nano optical surface relief structures. These technologies include, but are not limited to, analog holography and other laser recording techniques.The intricate pattern made up of micron and sub-micron elements which are created by these phenomena make it possible to create a fully three-dimensional image, or a directional diffuser, that has a specific beam profile (flat, gaussian, batwing) and performance angle characteristics. 

MesoOptics diffusers can be extremely efficient, in some cases transmitting greater than 90 percent of the incident light with low backscatter. Equally important, such diffusers may exhibit either isotropic or anisotropic diffusion characteristics. That is, they may diffuse light equally in all directions about the incident beam axis, or they may preferentially diffuse the incident light in a given direction.


How does MesoOptics solve some of the technical obstacles of traditional diffusers?

Zero-order beam

When a beam of light illuminates a diffraction grating (or other diffracting material) it is diffracted into multiple patterns, where each pattern is referred to as an order. ‘Zero-order’ refers to the undiffracted portion of the beam that is simply transmitted or specularly reflected by the diffraction grating. 

Applied to diffusers, zero-order refers to incident light that remains unscattered or not diffused after transmitting through the diffuser. 

In architectural luminaire design, a common role of diffusers is to obscure lamp images. To be useful in this application, diffusers must therefore exhibit total extinction of zero-order light. Philips Ledalite MesoOptics are designed to accomplish this.

Chromatic dispersion

Chromatic dispersion is the separation of light into its various wavelength components or colors. 

Diffusers must be properly engineered or they may exhibit rainbow fringes around lamp images because of dispersion. These fringes are similar to what would be seen when looking at the lamp through a glass prism. Philips Ledalite MesoOptics are designed to completely eliminate chromatic dispersion, regardless of the lamp type or dimensions.


How is MesoOptics manufactured?

When examined using microscopy, the master reveals a fine-structured surface relief pattern. This is the pattern created by Philips Ledalite’s proprietary recording and processing regime.It is this surface relief pattern that creates the performance properties of MesoOptics.

 

 

 


How durable is MesoOptics?

Ultraviolet resistance

The plastic materials used in Philips Ledalite MesoOptics are designed to withstand ultraviolet emissions from fluorescent and high intensity discharge lamps without premature yellowing or discoloration.

Heat resistance

Philips Ledalite MesoOptics can be manufactured using different plastics for various applications including polycarbonates and polyesters (used in theatrical lighting color filters and diffusers) that can withstand temperatures of up to 400°F before softening. 

Mechanical strength

Philips Ledalite MesoOptics can be produced in both plastic sheets and films. Where required, these films can be laminated to rigid plastic or glass substrates. 

Cleaning and care

Caring for products with MesoOptics materials should be relatively simple, provided a few precautions are taken. When handling MesoOptics materials / products, it is advised to wear cotton gloves and handle by the edges only. The microscopic surface pattern is sensitive to the volatile oils in finger marks which can degrade the MesoOptics material if they are not removed. If finger marks do get on the surfaces, they should be removed immediately according to the following cleaning instructions: 

  • Use a solution of warm water and a mild, liquid dish detergents (such as Sunlight)
  • Avoid detergents with hand-softeners or anti-bacterial agents
  • Do not use Windex or other glass-cleaners
  • Do not use Acrylic cleaning polishes
  • Use a soft, non-abrasive cloth and wipe the water/detergent solution along the grain of the MesoOptics material
  • Rinse once with warm water, then rinse again with distilled water
  • Allow material to drip dry by standing it up on one end or blow dry with a hairdryer on low heat
