In "Star Trek" (2009), why does one of the Vulcan science ministers state that Spock's application to Starfleet was logical but "unnecessary"? Or if anyone knows of a coating process that can be used on a formed piece of aluminum that would be good for reflecting UV. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Fermat's principle to prove the law of reflection, Reflection at intersection of two mirrors. Thus measurements of household aluminum foil reflectivity spectra on both bright and matte sides were undergone. Diffuse and total reflectivities were acquired, for two samples each time.

If it is like a mirror it will be very good. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Like all electromagnetic radiation, these wavelengths can be transmitted, reflected, absorbed, or scattered by substances they encounter. Aluminium is rarely used as an uncoated reflective surface, the mechanical and environmental properties are poor. How well depends on how shiny it is. Can the President of the United States pardon proactively? Can we trap living cells in optical tweezers? However, if the aluminum is on the Back Side of a piece of glass, the glass will absorb most of the UV light and therefore, No, a back-face mirror will not reflect much of the UV light. Metallic surfaces will reflect much of the radiation, while some of the higher energy rays may penetrate a ways and then be absorbed. reply from potential PhD advisor? UV-C is absorbed by ordinary window glass, and reflected by metallic foils (witness the gold foil … Quick link too easy to remove after installation, is this a problem? Stack Exchange Network Stack Exchange network consists of 176 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. It would be used as a reflector/concentrator from a UV bulb. How to solve this puzzle of Martin Gardner? Is this a correct rendering of some fourteenth-century Italian writing in modern orthography. Household aluminum foils was chosen as reflective material to build the concentrator. The question seems straightforward - will Al foil reflect UV at 240nm? Why did mainframes have big conspicuous power-off buttons? Using aluminium foil as a reflection for UV at 240nm [closed], “Question closed” notifications experiment results and graduation, MAINTENANCE WARNING: Possible downtime early morning Dec 2/4/9 UTC (8:30PM…. Why do I need to turn my crankshaft after installing a timing belt? TABLE 1 MATERIAL REFLECTIVITY e-PTFE 95% Aluminum—sputtered on glass 80% Aluminum foil 73% Stainless steel (various formulas) 20 – 28% A common material used in commercial UV disinfection systems is stainless steel. Could you clarify what you intend and what your question is? Please check your Tools->Board setting. This can slightly reduce the above values, or restrict the coating to UV / Visible use. The answer is "yes". Where is this Utah triangle monolith located? What is this part of an aircraft (looks like a long thick pole sticking out of the back)? These measurements were done using an integrating sphere, over a 250–2500 nm range. Aluminium does have a dip in its reflectivity in the 700nm – 900nm spectrum. Aluminum is a good reflector of UV, visible and IR light. What modern innovations have been/are being made for the piano. Can it be justified that an economic contraction of 11.3% is "the largest fall for more than 300 years"? The obtained results … In Monopoly, if your Community Chest card reads "Go back to ...." , do you move forward or backward? Will aluminium foil or sheeting reflect UV light at 240nm being used as a disinfection cell for bacteria in water. It only takes a minute to sign up. Unless the glass is special glass that has a a high transmissivity for UV. whenthepowderedmetal(forexample,aluminum)isappliedwitha lacquer, the total amount ofultra-violet radiation in proportion to the visible and the infra-red rays is relatively lower in the reflected rays By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. How does the reflection coefficient change with scattering and absorption? Will aluminium foil or sheeting reflect UV light at 240nm being used as a disinfection cell for bacteria in water. Can a polarizing beam splitter cube be used to replace two polarizers? This choice raised the question of which side to use. Part of reflection/transmission of an impinging beam under 90°.

Therefore thickness of the interfering material is of great importance. I'm not sure what it is you are asking here. A protective layer of MgF2 or SiO2 is needed. How did a pawn appear out of thin air in “P @ e2” after queen capture? How to consider rude(?) While this surface is highly resistive to microbial growth, it only has 20 - 28% reflectance of UV light. Update the question so it's on-topic for Physics Stack Exchange.
