(57) Abstract:Usage: to create reflective surfaces illuminator lasers. The inventive application of thermal insulation material as reflective coatings that can withstand high shock loads without loss of the reflection properties of 100% in a wide wavelength range 200 - 1300 nm, withstands temperature changes and allows secure it on any basis. 1 Il. The invention relates to the field of lighting and can be used to create reflective surfaces, lights lasers, where high reflectivity as UV radiation and IR radiation, the radiation resistance and mechanical strength of the coating.Under the radiation resistance is the ability of the irradiated surface to retain its physical properties and does not deteriorate under the influence of powerful light radiation.Currently, the lights lasers as reflective coatings are widely applied polished aluminum construction reflector of aluminum is described in the monograph by D. Birnbaum 
In addition to the complexity of the polishing aluminum coating has a low resurvey pulses. It should be noted and relatively low reflectance aluminum 80% in the wavelength interval 200-1300 nm.Significantly, these problems are eliminated by using the composition to obtain a reflective coating containing a dispersion of barium sulfate /SO4/ in an aqueous solution neorganicheskoi binder of sodium silicate  He has more than aluminum, the reflectance in the UV-radiation 90%, but tests have shown that when a large amount of water BaSO4quickly precipitates, because he has a relatively high density, and therefore for the application of such compositions need periodic stirring. At low water content of the coating is dense and more durable, but it is more difficult to manufacture, because the viscous compositions bad sprayed with a spray gun.Also known composition to obtain a coating that reflects ultraviolet light, on the basis of silicon dioxide containing water, sodium silicate in the following ratios, wt.SiO235,5 65
H2O 27 59.The composition is well reflects UV radiation. By using a binder having a high radiation resistance, durability, good adhesion with SiO2and mataj impact strength reflective coatings, the impossibility of application of the composition on some plastic surfaces due to poor adhesion to him, the inability of the coating on hard surfaces, destruction of the coating as the passage of time as a result of changing ambient temperature.The problem solved by the present invention is the creation of an effective reflecting surface capable of withstanding high impact loads without loss of reflective properties in a wide wavelength range from 200 to 1300 nm, can withstand temperature changes and enabling its attachment on any basis.This object is achieved by the application of known insulating material based on amorphous quartz fiber as reflective coatings.The drawing shows a graph of coefficient of the diffuse reflections [% of wavelength l [nm]
Specified heat insulating material has found use in high temperature furnaces to prevent the destruction of the frame of the furnace. According TL1-596-117-86 and TL1-596-180 - 83 this insulating material is based on amorphous quartz fiber. Working temperature of the material from -150 to +1100oWith a density of from 0,130 to 0,300 g/cm3. Material b is Dah, where the light scattering is minimized. In our case uses a completely opposite property amorphous fused mass of glass scattering of light.Due to the presence of air microbubble this material is a good heat insulator. For light waves, this rough surface is a good diffuse reflector, despite the presence of microcotton that a good light, and microcracks, which are light traps.Measurement of diffuse reflectance r was carried out using a broadband radiation source and classical fotoshare an integrating sphere, inside of which was placed the analyzed sample. The analyzed samples had geometric parameters HH. Using photometric instruments were recorded radiation in the wavelength range 200-1300 nm. The proposed material was subjected to irradiation of the light flux intensity P0,5 mW/cm2. In the 200 inclusions sample having a thickness of 10 mm, is not destroyed. The dependence of the reflection coefficient r as a function of wavelength is shown on the drawing. From the drawing it appears that by increasing the wavelength from 200 to 1300 nm, the reflectivity of the sample as a coating, reflecting light in a wide wavelength range, perspective, where broadband pumping light, stability, reflective properties and radiation resistance, for example, laser technology.The inventive reflective coating according to the experimental data is in the wavelength range 200-1300 nm reflectance of 100% For comparison reflecting coating [2,3] in a narrow wavelength range 240 -300 nm has a reflectance r90%, and 95%. At trial the alleged cover on the radial stop bone radiation intensity P of 0.5 mW/cm2the sample thickness of 10 mm did not stand razrushivshij 200 inclusions. Technologically difficult to put a strong reflective coating on the inner surface of the illuminator, because it requires a high adhesion to the base material. All this can be compounded by the inaccessibility of the substrate surface during the deposition process. This problem is solved in the case of the proposed use of the material. From it you can cut the reflector of any shape and mechanically secure anywhere illuminator. The application of insulating material based on amorphous quartz fiber as diffuse reflective coatings.

SUBSTANCE: proposed device that can be used for dissipating electromagnetic radiation, such as light, radio waves, X-rays, as well as for dissipating particle streams is, essentially, multilayer screen some of whose layers are deformable ones. Electric field is built up between two electricity conducting layers due to voltage applied to these layers. In the process conducting layers are split into segments and separate electrodes are brought to respective layers. Voltage applied to separate segments permanently varies with the result that electric field produced is nonuniform and deformable layers are embossed due to nonuniformity of attractive forces between electrodes, this embossed pattern permanently changing its configuration. Radiation (light of different ranges, radio and electromagnetic waves, particle streams) passed through screen or reflected therefrom dissipate due to optical nonuniformity. Kind of dissipation continuously varies due to changes in embossed pattern. Segments of conducting layers can be energized obeying different laws including pseudorandom one.
