2), magnesium fluoride (MgF 2o Our use of multi-axis coating chambers gives us the capability to uniformly coat polygons and spinners, as well as complex and unusual shapes. The team is working to develop a process to treat an aluminum surface on a scale as large as 1 meter (m) in diameter. for aluminum are 0.65 and 5.5, respectively, resulting in a visible reflectance of ~90% for the bare surface. 2), yittrium oxide (Y 4), aluminium nitride (AlN) or its mixture. ENHANCED ALUMINUM for UV. This description comprise in the remainder be described with reference to accompanying drawing more specifically set forth comprise be to those skilled in the art optimal mode of the present invention of the present invention complete and enforceable open, wherein: Fig. 3), ytterbium oxide (Yb This simple, low cost solution to routing light can also provide some measure of light gathering, focusing, or collimation if applied to the appropriate curved surface. But, in a particular embodiment, these selectable layers can be dispensed from this lamp 10.Such as, in the alternate embodiment in Figure 5, the inner surface 13 that this reflecting layer 14 is directly set to this housing 12 does not exist other layer any, and meanwhile, this optical interference laminated coating 16 is set directly on this reflecting layer 14 and there is not other layer any. 3n Left to right: Javier del Hoyo (GSFC), Emily Witt (U. of CO), and Nicholas Nell (U. of CO). dichroic reflectors characterised by coatings, 中国科学院国家天文台南京天文光学技术研究所, TOSHIBA LIGHTING & TECHNOLOGY CORPORATION, Ultra wide band high reflectivity mirror membrane system of astronomical telescope and preparation method thereof, A lighting unit having a lamp and a reflector, Mirror with dichroic coating lamp housing, Wide-angle color temperature-adjusting cold reflector for shadowless lamp, VO2/TiN Plasmonic Thermochromic Smart Coatings for Room‐Temperature Applications, Plastic optical component having a reflection prevention film and mechanism for making reflection prevention film thickness uniform, Method for making optical lenses having an anti-reflection coating and the optical article produced thereby, Broadband omnidirectional antireflection coatings optimized by genetic algorithm, Process of decreasing reflection of light from surfaces, and articles so produced, Optical interference coating and lamp using the same, High endurance near-infrared optical window, Method of forming thin-film structure by oblique-angle deposition, Method for producing a substrate coated with a stack including a conductive transparent oxide film, Antireflection film-equipped substrate and its production process, Mirror for reflecting light of selected frequency and method for forming the same, Optimization of antireflection coating for VO2-based energy efficient window, Transparent substrate with thin film laminate, Method and structure of optical thin film using crystallized nano-porous material, Thermally stable multilayer mirror for EUV spectral range, Rugate filter made with composite thin films by ion-beam sputtering, Methods for producing omni-directional multi-layer photonic structures, Titanium oxide transparent film having at least one of aluminum and aluminum oxide and having a rutile structure, Incandescent lamp incorporating extended high-reflectivity IR coating and lighting fixture incorporating such an incandescent lamp, Design and development of ITO/Ag/ITO spectral beam splitter coating for photovoltaic-thermoelectric hybrid systems, Entry into force of request for substantive examination, Invention patent application deemed withdrawn after publication. Unfortunately, no one has developed a coating that effectively protects and maintains a mirror’s reflectivity in the 90- to 130-nm range, also known as the Lyman Ultraviolet range, a spectral regime rich in astronomical targets and spectral lines, including potentially habitable planets beyond our solar system. Aluminum is the metal with the broadest spectral coverage. Reflectivity over the desired wavelength range is the primary factor in choosing a metal coating material, though environmental stability plays a factor, particularly when no overcoat can be tolerated. Reflector lamps and their methods of manufacture are provided. In a specific embodiment, lens 22 can be sealed (such as, flame sealing) in this reflector shell 12 to form airtight chamber, such as, shown in Fig. We can also offer custom sizes. 15. methods according to claim 15, is characterized in that, the described low-index layer that replaces and high index layer improve the reflectivity in described reflecting layer.

They scratch very easily, making them difficult to clean, and tend to oxidize over time (silver in particular). ), Enhanced single or multiband coverage, <400 nm="" to="" 5000nm=""    ="">, High performance coatings of consistent quality, Low mechanical stress from precision-figured optics, Low temperature coating process for optic safety, Common substrates coated include: Aluminum, Beryllium Silicon, ULE, Zerodur. 2 is the perspective view of another exemplary lamp according to an embodiment of the invention; Fig. The minimum in the reflectance curve around 800 nm is due to a phonon resonance and can only be overcome by a dielectric protective coating. High index layer 17 can change according to the material in these layers with the thickness of low-index layer 15.In most embodiment, high index layer 17 and the thickness of each in low-index layer 15 can be about 100nm to about 400nm (such as, about 150nm to about 350nm).In a particular embodiment, multiple low-index layer 15 replaced can form optical interference laminated coating 16 with high index layer 17, and total geometric thickness of this optical interference laminated coating 16 is about 1 μm to about 15 μm (such as, about 2 μm to about 10 μm).The thickness of each alternating layer 15,17 and the gross thickness of this optical interference laminated coating 16 can be controlled to provide generally flat reflectivity curve in whole visible wavelength region.Thus, this design is different from the quarter-wave design relying on reference wavelength. Using vacuum deposition technology, we deposit a variety of materials to enhance the spectral properties of an optical system. Previous studies indicated that the use of xenon difluoride creates fluorine ions that tightly bind to the aluminum surface, preventing the oxidation that decreases reflectivity. However, aluminum … The application also mainly provides the method for the formation of reflector lamp.In one embodiment, reflecting layer (such as, comprising aluminium) can be formed on the inner surface of this housing.Subsequently the low-index layer replaced and high index layer can be deposited on this reflecting layer, to form optical interference laminated coating.Before or after this reflecting layer of formation and/or this optical interference laminated coating, light source can be arranged in this housing. |. Dielectric mirrors, however, perform well for laser damage threshold (LDT) testing with critical preparation of the optical surface and selection of coating materials. 6. reflector lamp according to claim 1, is characterized in that, described high index layer comprises niobium oxide. What are the characteristics of the Solar System? Improved reflectivity in itself would bring enormous gains in throughput, and the benefits of more capable optical designs enabled by higher reflectivity would increase sensitivity. Note that the coating used in the HST mirrors consisted of Al protected with magnesium difluoride (MgF2). The reflectance in the VIS and UV spectral Embodiments of the invention relate to the preparation method of a kind of reflector coat and a kind of this reflector coat for using in reflector lamp. As selection, high index layer 17 can have the refractive index of the refractive index higher than low-index layer 15.Such as, high index layer 17 can have the refractive index of about 1.7 to about 2.8 (being such as, about 2.0 to about 2.7 at 550 nm) at 550 nm.In a particular embodiment, high index layer 17 can have about 2.05 to about 2.4, the refractive index of such as about 2.1 to about 2.3.Such as, high index layer 17 can be the thin layer comprising arbitrary suitable material, and this arbitrary suitable material is such as niobium oxide (such as, Nb I will contact you directly for further assistance. As a result, we provide bare metal coatings for some customers, packaged carefully to protect the surface and facilitate easy handling.
