Par nature incolore et d'une limpidité exceptionnelle, il peut être teinté dans une très large palette de couleurs. OP-4 acrylic sheet transmits a high percentage of UVA and UVB light. The films were characterized spectroscopically using FTIR which illustrated that the decrease of the intensity of transmission spectra of (50/50 PMMA/PVAc) blend after exposure to UV radiation for 24 hours was lower than that of PMMA and PVAc. Just as a quick aside, and to demonstrate how scattering does reduce the measured transmission through theses plates with my setup, I did a simple experiment. (For reference, the human eye is sensitive to light between about 400 nm [blue] and 700 nm [red]). I've re-run the 2 PMMA plates for transmission, along with a Hoya NDx8 ND filter. Optical transmission of PMMA (polymethylmethacrylate) POF (polymer optical fibre) in the spectral range from 280 to 450 nm is investigated with a high radiation emission source comprising a mercury lamp delivering 40 W/cm 2 at the PMMA POF launch face. PMMA also finds used in solar panels as cover materials thanks to its excellent UV resistance and excellent light transmission allowing high energy conversion efficiencies. Plastic sheeting with unique UV characteristics is often used where UV rays are an issue, whether it is UV filtering or transmitting. PMMA on SiO 2 on the light transmission by FTIR and UV-Vis-NIR spectroscopy for high efficiency solar cells. Blend films of PMMA and PVAc with different concentrations have been prepared by casting method, and they were exposed to UV and filtered radiation for 24 hours.

The aim of the present work to investigate the effect of UV-irradiation on the optical properties of PMMA within period of time (24,72,and120hr.). Unlike glass, it has a non-ionic, inert surface to minimize reactivity, denaturation, agglomeration, delamination and other traditional glass concerns. Ultraviolet light is key to many modern analytical and diagnostic test methods in healthcare, life sciences, and chemistry. Our results have demonstrated that PMMA-encapsulated UV filters have improved safety, photoprotective ability and photostability. Acrylic/Styrene. Recently, a customer consulted a portable light transmission meter. Polymethyl methacrylate (PMMA or "acrylic") cuvettes extend that range to about 300nm, or slightly into the near UV range, and have slightly greater chemical compatibility. However, this can result in some functions no longer being available. This outstanding clarity enables the use of PMMA in many different optical and related applications. This makes TOPAS COC the best UV transparent plastic for a growing list of diagnostic, microfluidic, and point-of-care products.

Linshang manufactures a series of optical instruments on sales to test the infrared transmission and UV transmission for PC,glass,PMMA and other materials. Many medical plastics are poor barriers to moisture and chemicals, leading to a short shelf life. PMMA also finds used in solar panels as cover materials thanks to its excellent UV resistance and excellent light transmission allowing high energy conversion efficiencies. Acrylic. We have optimized our medical polymers for the best available UV transparency by eliminating UV stabilizers, and thus we do not recommend use in repeat sterilization or other long term UV exposure applications. TOPAS Advanced Polymers is ISO 9001 and ISO 50001 Certified. Scanning electron microscopy (SEM) analysis was used to evaluate the influence of radiation on PMMA fracture behavior. UV light, a form of energy, is defined as light having wavelengths between 100 nanometers (nm, 1 billionth of a meter in length) and 400 nm. Both types of samples show high transmission above ~400 nm wavelength, which is expected as PMMA finds wide applications as an optically transparent window material.
