Fluorite typically glows a blue-violet color under shortwave and longwave light. Some specimens are known to glow a cream or white color. Many specimens do not fluoresce. Fluorescence in fluorite is thought to be caused by the presence of yttrium, europium, samarium [2] or organic material as activators. UV Filtering Acrylic. UV filtering acrylic is one of the most popular specialized acrylic sheeting solutions on the market today. Although UV filtering plexiglass can not completely prevent colors from fading or darkening, it does filter out up to 98% of harmful UV light. This makes it the ideal plastic sheet material for protecting artwork Typically made of PMMA (polymethylmethacrylate), acrylic light pipes will be superior due to their: High light transmittance – PMMA allows 92% of light to pass through it, which is more than glass or other plastics. UV stability – because PMMA also has a high resistance to UV’s damaging rays, it’s suitable for outdoor applications or Strong, durable and highly versatile, acrylic sheets are now the preferred material in a huge range of applications. One of the huge advantages of clear acrylic is the fantastic levels of optical clarity. Compared to glass, which delivers below 90%, acrylic allows up to 92% of visible light that it comes in contact with to pass through. We strongly recommend that anyone using UV light to disinfect equipment, surfaces, or air, follow all recommended health and safety precautions and to avoid direct exposure to UV light. In summary: UV-C radiation of skin, eyes, or any body part should be avoided. Always wear appropriate PPE when handling un-shielded UV-C radiation sources (e.g . most tubes need replacing every 6 months to one year depending on the manufactorer. i suggest you speak to arcadia john regarding uv lighting. uv light does not pass through dense mesh, glass, perspex, plastic, fabric etc etc. 0.01 Snow Corn Snake; Pip. 2.0 Royal Pythons - Normals; Chap & Cobe. Opacity and transparency both deal with the amount of light that can pass through an object, in this case acrylic or plexiglass plastic. Opaque Acrylic: Opaque acrylic will let minimal to no light through. An opaque piece of plastic will completely block out light when placed in front of a light source. UV AR coatings can be a sensible way to augment UV protection – but only if the majority of rays are blocked by the lens. The fact is, anti-reflective (AR) coatings are designed to increase transmission of light through lenses. Without a UV blocking lens material, UV AR coatings will actually increase UV transmission coming directly Does anyone know if I should leave the plates open under uv light or I can close the plates. The protocol I watched online had gheir plates closed, but then I keep some articles say UV cannot Plexiglass is a type of acrylic sheet that refers to different glass-like products manufactured under different names. In earlier years, manufacturers produced acrylic sheets under the name plexiglass. Currently, manufacturers create plexiglass acrylic products but term them under names such as acrylate, crylux, lucite, and perspex.
