We recommend you find a mechanical means of securing the diffuser into your system, for example using the natural tension of a film on curved surface. We offer pressure-sensitive adhesive (PSA) as an option but this process is difficult and you may experience the incorporation of air bubbles during the lamination process.

There are currently two different types of DTF products, one is a 20⁰ bend-off axis material for visible or white light and the other is a 10⁰ bend-off axis for 810nm (IR) LEDs.

Luminit’s DTF (Direction Turning Film) is a non-symmetrical linear micro-prismatic that imparts a 20-degree shift in the angle of a semi-collimated light source. The DTF works well with LED light sources that utilize secondary optics. Some applications include recessed can lights to allow for more wall washing, pathway/stair lighting to reduce glare and increase ground illumination, and pool lighting to increase illumination of the bottom.

Yes, Luminit optical diffusion films are so precise that beam shaping is possible. Our patented holographic master recording process allows a variety of circular and elliptical light patterns. Standard circular angles range from 0.5˚ to 100˚ FWHM. A wide variety of standard elliptical angles, ranging from 10˚x0.2˚ to 95˚x35˚, are available.

Luminit's unique LED optical diffuser material is available in a variety of circular and elliptical angles from 1° to 100° on thin film or rigid substrates. Standard angles include: 80ºx50º, 60ºx10º, 80º, 60º, 40º, 30°, 20°, 10°, and 5°. We also offer non-standard angles, including 1°, 2°, 3.5°, 30°×35° 40°×1°, 60°×1°, 69°×30°, 75°×45°, and 90°×10°.

Since our microstructures are random and non-periodic, the Light Shaping Diffuser® is not wavelength-dependent, so it works well from 400nm to 700nm.

Light Shaping Diffusers® are micro-structures pseudo-randomly embedded on a substrate (such as film) which perform optical diffusion. When applied to a lighting structure, the Light Shaping Diffuser® can manipulate light by changing the direction of its energy. This allows our Light Shaping Diffusers® to clean up and shape a light beam to suit a particular purpose.

Because we replicate our holographic LED diffusers directly onto rigid panels instead of through a lamination process, our LED diffuser panels will not become brittle, peel or yellow over time.

This depends on the angle of divergence and spacing of the light sources. With 110° Field of View, surface mount LEDs, the relationship is around 1:1. That is, if the LEDs are spaced 1 inch apart then you will need a little more than 1-inch distance from the LEDs to our largest diffuser angles. Here is an illustration demonstrating the ratios with various angle diffusers.

With SimpleSet technology, manufacturers can configure a wide array of parameters quickly and efficiently—saving time, reducing the amount of steps needed and simplifying their workflow. The system can be easily integrated into your assembly process, either right in the production line or as a separate step in a dedicated work cell for batch processing.

Choose spot lights to illuminate a single feature, like a tree or architectural element. Flood lights wash an entire area with light.

Thin-film Light Shaping Diffusers® are available in rolls, sheets or parts cut to your specifications. Standard rolls are 20” wide and 500’ long. Strip rolls are also available in your specified width. 24"x 24" rigid sheets are available on polycarbonate in various thicknesses. Contact sales for a quote.

The transmission efficiencies of Luminit optical diffusers are rated between 85-92% (depending on the angle). This very high-efficiency rating is due to the fact that our technology is based on diffractive microstructures. Smaller angle diffusers have the highest transmission.

We suggest you handle the diffuser with clean latex gloves. High angle diffusers are very prone to damage due the height of the microstructures. They can be cleaned carefully using optical wipes and ethanol using the industry-standard “drop and drag” technique.

Our display Brightness Film (DBF) is a light management film that increases the brightness of LCD displays. DBF is a prismatic structure with either a 1, 2, 3.5, 10 or 20-degree diffuser on the other side of the film. DBF is also available without the diffuser.

Light Shaping Diffusers® are often applied in architectural lighting, can lights, decorative lighting, pool lighting, set/event lighting and wall wash lighting where the effects of the Light Shaping Diffuser® can be quite dramatic. LED Light Shaping Diffusers® are also used in illumination systems such as aircraft inspection lights; backlit systems such as cellphone and PDA displays; LCD screens and more. One of the most common uses for our light diffusers is to eliminate hot spots on LED light strips.

Yes, you can layer multiple sheets of DTF to increase the angle of redirection; however, there will be significant transmission loss.

Yes, our Light Shaping Diffusers comply with RoHs standards. An environmental compliance statement can be downloaded here.

FWHM is an abbreviation for Full-Width Half-Maximum which is the angle of diffusion that would be seen after a collimated laser passes through the diffuser.

No, since our technology is based on a surface relief pattern, these parameters are not dependent on the thickness of the substrate. However, there are inherently additional transmission losses if very thick substrates are utilized (Beer’s Law).

Our blue protective film is used to protect the diffuser during transit to reduce the chances of scratches. We advise customers to remove the film within three months of arrival. The reason for this is that there is a chance that the adhesive on the film can cure or harden and stick to the diffuser.

Luminit Monolithic Glass Diffusers are made with an etching process, while our Glass on Glass light diffusers have pseudo-random microstructures that are cast and cured onto the surface of the glass. Temperature is one of the factors that differentiate the two. Our Glass on Glass diffusers are stable up to 500° C and are suitable for high-temperature laser applications. Monolithic glass is also rated for high temperature but is more suitable for lighting applications.

Yes, Luminit Light Shaping Diffusers® are commonly used as an LED strip light diffuser to eliminate the hotspots without a significant reduction in the amount of the light, provided that the diffuser is placed a sufficient distance from the LEDs. A rule of thumb is that the diffuser must be at least as far away from the LEDs as the LEDs are spaced apart.

Direction Turning Films can be combined with Light Shaping Diffusers to shape and homogenize the beam in addition to changing the direction. The beam can be shaped in a circular or elliptical pattern dependent on the diffuser angle chosen. These light bending films enable off-axis placement of the incoming beam when direct line of sight is impractical. Applications include LED lighting, avionics displays, traffic signs/displays and LCD backlights. They are also used to change the light beam direction to light a wall, walkway or other lighting target.

Yes, our lighting diffuser film is approved by AMECA as meeting the three-year weathering test of SAE J576 for plastics used in optical lenses and reflectors on motor vehicles.

Luminit replicates diffusers on polycarbonate and acrylics (PMMA). We can also replicate our diffusers on glass products.

The diffuser has improved transmission characteristics if the microstructure side is facing the light source, but it has better source hiding characteristics if the microstructure side is facing away from the light source.

Yes, Luminit Light Shaping Diffusers® are available in various circular and elliptical angles in pre-cut sheet format for lower volume applications.

Though our LED diffuser sheets are often installed in outdoor environments, they are not waterproof. Submerging the diffuser film or sheet in water would dissolve the microstructures and render the diffuser unusable.
