< Topic >The nano- compound seal material and the optical guided wave material which designate the nano- particle which has the high refractive index which in optics can be relied on as the foundation are offered.SolutionsMainly the light-emitting diode (LED) with the high refractive index ...
A light emitting diode (14) sends light through a hemispherical diffuser (18) to a central light motor (22) which has a hemispherical entry (26) within a parabolic surface (30). The majority of the light is reflected parallel to the optical axis and is further reflected by a front surfac...

Which color has highest refractive index? What is an instrument that separates light into various wavelengths? What causes the dark bands observed in a solar spectrum? What color bends the most in a prism? How can white light be separated into different colors? What is the opposite of...
Production quantities of polyvinyl chloride (PVC) are among the highest of any plastic. Because of the versatility of this material, it is nowadays found in a wide variety of products used in everyday life. PVC therefore has very great economic importance. Intrinsically, PVC is a plastic which...
has no contact with the vessel walls of the melt crucible. This is achieved by cooling the vessel walls with a cooling agent, so that a solidified crust (skull) of specific material is formed. Because of the use of oxygen and/or ozone for bubbling during the whole process, it is ...
