In 2023, fluorescent T5 & T8 lamps and compact fluorescent lamps were phased out in accordance with EU directives. If you have fluorescent in your facility, it is a good idea to look at future-proof alternatives now. We are happy to help you find a sustainable solution!
英文名称:Plastics — Methods of exposure to laboratory light sources — Part 3: Fluorescent UV lamps 标准状态:废止 发布日期:1994-09-22 文档简介 ISO4892-3:1994EN标准规定了塑料在实验室光源暴露下的方法,其中第三部分涉及荧光UV灯。该标准的主要目的是确定荧光UV灯在塑料材料上的紫外光输出和光谱分布,以评...
many reviews. In principle, the incidentlight beamtransforms the sample into an excited state. The thermal deactivation process from the sample induces the changes in the temperature of the thin layer of the coupling medium surrounding the sample. The coupling medium could be atmospheric air or ...
How to get the most value from your new lamps Make sure that you are using the lamp that is most efficient for the emulsion you are exposing. Many exposure systems let you use lamps with different spectral output. If you change types, make sure your equipment has been adjusted for the ...

The second is the ac line voltage detector and the battery charger. By transistor-Q1 will open circuit when voltage from AC line power still. (at its base will has voltage not exceeds 0.7V) and when not have voltage from power supply Q1 will close switch down, cause the lamps glow. ...

Understanding these phenomena is increasingly important as the light from modern lamps, such as LEDs, typically contains a greater percentage of blue light, making them more biologically effective, and the use of devices that emit artificial light (e.g., smartphones) becomes more pervasive4,26,...
Rays of ultraviolet light emanating from lamps 40 pass through the mold members 78 and act on a lens forming material disposed in the mold cavity 82 in a manner discussed below so as to form a lens. As noted above, the rays of ultraviolet light may pass through a suitable filter 54 or...
However, it both control signals are varied from non-zero values, a variety of perceptibly different colors may be produced (e.g., in this example, at very least, many different shades of purple are possible). In particular, perhaps a particular desired color (e.g., lavender) is given...
