The high-performance holographic (LSD) diffusers have an extremely high transmission -up to 92% - combined with a very good diffusion. 3M Product Number . They have a surface with completely random, non-periodic structures that can be thought of … In optics, a diffuser (also called a light diffuser or optical diffuser) is any material that diffuses or scatters light in some manner to transmit soft light.Diffused light can be easily obtained by reflecting light from a white surface, while more compact diffusers may use translucent material, including ground glass, teflon, opal glass, and greyed glass. Technologies. Holographic diffusers are an improvement on these technologies and enable limited production of light distribution patterns, but only offer Gaussian-like intensity profiles and circular or elliptical patterns. 1.

Holografix ™ is a unique family of products with a polyester film base that has been embossed and metalized to bring out a bright, vibrant, multi-dimensional pattern. Holography is the science and practice of making holograms. Here are some of the uses of Engineered Diffusers ™ How we define diffuser angles. The effective size of the diffuser was found to be 10.8×9 cm 2, which results in a convergence angle of approximately 8.5° during reconstruction. Reduced back diffusion was achieved by lamination and index matching procedures which minimized the formation of Bragg planes parallel to the film surface. Un hologramme pour le roi est un film réalisé par Tom Tykwer avec Tom Hanks, Sarita Choudhury. White. diffuser: Recessed back from the opening aperture, the extruded high performance lens seems to float in the housing.

A hologram is a photographic recording of a light field, rather than an image formed by a lens. The angle λ shown in FIG. The time-scheduled exposure energies at wavelengths of 633, 532, … 123. distribution of diffused light. If the driver ’s eyes are outside of the eyebox, the display is not visible. The light guide, for example, may include a diffuser and/or an optical isolation layer to further enhance the optical characteristics of the display. 3M™ Diffuser Film 3635-70, White, 48 in x 50 yd. Vente au mètre linéaire du film Holographique Filmapix. It is important to note that diffusing angles are given for a collimated input beam and angular divergence will vary for different incidence angles. Diffuser film by a company called Luminit and as you can see from their website, they do a lot more than diffuser films. The filter is quite opaque and reminds me of Zebralight diffused lens.
