LS108 Spectrum Transmission Meter 1.Purple light Peak wavelength: 395nm;Blue light Peak wavelength: 430nm;Visible light … We proposed therefore that these PMMA-encapsulated UV filters can be used as ingredients for sunscreen products in the future. New systems take advantage of the design freedom of TOPAS COC and its high UV transmission. But without UV transparent materials, many forms of analysis would be impossible. Although ultraviolet (UV) radiation amounts to only 3% of the total radiation that reaches the earth, it is energetic enough to cause chemical reactions, weathering of polymers, fading of certain … Le PMMA (Polymétacrylate) est un thermoplastique transparent et rigide. UV transparent microplates, cuvettes and other disposables use TOPAS COC instead of PP, PS, PMMA, PVC or polycarbonate whenever high transmission is key to consistent results. Unlike glass, it has a non-ionic, inert surface to minimize reactivity, denaturation, agglomeration, delamination and other traditional glass concerns. VISIBLE LIGHT TRANSMISSION In colorless form,Plexiglas ® sheet is as transparent as the finest optical glass.Its total light transmission is 92%, and its measured haze averages only 1%. abaqueplast propose une gamme de plaques en acrylique PMMA coulé (plexi) noir et blanc, gris et blanc LED, noir et blanc LED de la marque Altuglas® appelée Night & Day.

The UV disposable cuvettes we buy here are from BrandTech; below is a UV transmission chart for various materials from one of their marketing brochures (click image to enlarge): They've clearly had success in developing materials with even better UV transmittance (green and yellow curves) than PMMA (red curve), but it looks like the latter may be your best option. Please note that additional wavelength ranges and other plastics can be viewed below. Light weight is another advantage of COC, of course, as is the ability to create more sophisticated and complex designs than glass or other polymers. Consequently, (50/50 PMMA/PVAc) blend has improved the degradation of its homopolymer. Les paramètres de transmission et de diffusion de la lumière peuvent être modifiés à la demande. UV transparent microplates, cuvettes and other disposables use TOPAS COC instead of PP, PS, PMMA, PVC or polycarbonate whenever high transmission is key to consistent results. Linshang manufactures a series of optical instruments on sales to test the infrared transmission and UV transmission for PC,glass,PMMA and other materials. Polycarbonate. However, this can result in some functions no longer being available. Fortunately, Polyplastics and TOPAS Advanced Polymers provide a line of glass-clear, medical grade plastics with high UV transmission so that tests utilizing UVA, UVB, and with the right grade, even UVC down to 220nm can be carried out with confidence. Recently, a customer consulted a portable light transmission meter. Le PMMA (Polymétacrylate) est un thermoplastique transparent et rigide. These samples were irradiated UV-source for a period of time by (24,72,and120hr.). You can change these settings at any time. 2. It offers high levels of UV light transmission and strong resistance to degradation caused by UV light. Le PMMA coulé représente la qualité supérieure de ce matériau, la tenue dans le temps sera supérieure à celle du PMMA extrudé. light transmissions through PMMA films of different layer thicknesses on SiO 2 substrates for solar cell applications using Fourier transform infrared (FTIR) and ultraviolet visible and near infrared (UV-Vis-NIR) spectroscopy. TOPAS COC medical grade polymers enable miniaturization of UV testing systems, eliminating the limitations of glass. UV-A light (320-400 nm) and UV-B light (280-320 nm) are used in many applications, from medical treatment to suntanning.
