In 1961, General Electric began selling transparent alumina Lucalox bulbs. Not surprisingly, a combination of these two materials in the form of the yttria-alumina garnet ( YAG) has proven to be one of the top performers in the field. Yttria is fully transparent from 3–5 micrometers, but lacks sufficient strength, hardness, and thermal shock resistance for high-performance aerospace applications.

For example, sapphire (crystalline alumina) is very strong, but lacks full transparency throughout the 3–5 micrometer mid-IR range. Currently available infrared (IR) transparent materials typically exhibit a trade-off between optical performance and mechanical strength. Basic applications include lasers and cutting tools, transparent armor windows, night vision devices (NVD), and nose cones for heat seeking missiles. Transparent ceramics have recently acquired a high degree of interest and notoriety. Synthetic sapphire – single-crystal aluminum oxide (sapphire – Al 2O 3) is a transparent ceramic Recent nanoscale technology, however, has made possible the production of (poly)crystalline transparent ceramics such as alumina Al 2O 3, yttria alumina garnet (YAG), and neodymium-doped Nd:YAG. Thus, they are generally opaque as opposed to transparent materials. Most ceramic materials, such as alumina and its compounds, are formed from fine powders, yielding a fine grained polycrystalline microstructure that is filled with scattering centers comparable to the wavelength of visible light. įor example, since visible light has a wavelength scale on the order of hundreds of nanometers, scattering centers will have dimensions on a similar spatial scale. The amount of light scattering therefore depends on the wavelength of the incident radiation, or light. While single-crystalline ceramics may be largely defect-free (particularly within the spatial scale of the incident light wave), optical transparency in polycrystalline materials is limited by the amount of light that is scattered by their microstructural features.
Such devices have found widespread use for various applications in the electro-optical field including: optical fibers for guided lightwave transmission, optical switches, laser amplifiers and lenses, hosts for solid-state lasers and optical window materials for gas lasers, and infrared (IR) heat seeking devices for missile guidance systems and IR night vision. Many ceramic materials, both glassy and crystalline, have found use as optically transparent materials in various forms from bulk solid-state components to high surface area forms such as thin films, coatings, and fibers.

The third step is a gel such as Base One Shining, which fits perfectly with the previous layers and adds shine to the nails.Transparent spinel (MgAl 2O 4) ceramic is used traditionally for applications such as high-energy laser windows because of its excellent transmission in visible wavelengths and mid-wavelength infrared (0.2–5.0 μm) when combined with selected materials – source: U.S. The cured gel layer of "Bonder" is a primer for the second step, which is building the layer: made with gel such as Base One Clear - V. The gel forms a protective filter between the nail and the gel which increases the adhesion of subsequent gels. Base Gel One Bonder) that increases the adhesion of the gel mass. Thanks to it used decorations will last longer, and we will longer enjoy their intensity. The top layer after wiping does not require additional polishing.īase One Line is a single-phase line, which thanks to the development from the best products combined in the right proportions, it can be used in a three-phase process.

HOW TO USE: spread the gel on the nail plate and cure in a UV lamp with power of 36 watts for 2 min. By eliminating the acrylic acid product is obtained having much more favorable effect on the nail plate than the standard UV gels.
Medium thick, self-leveling - provides a level of comfort.
With ease you can blend elements and combine with other gels or acrylics. Relevant setting of units makes that mass is durable and flexible, and at the same time has a very good adhesion to both, tip and natural nail plate.īase One Clear is a transparent gel, ideal to build the nail on tips as well as on the template. Base One gels were created according to a modern recipe that produces extremly durable polymeric sequences of gel mass.
