Since infrared light is comprised of longer wavelengths than visible light, the two regions behave differently when propagating through the same optical medium. Some materials can be used for either IR or visible applications, most notably fused silica , BK7 and sapphire ; however, the performance of an optical system can be optimized by using
If you want to take a white LED and get UV light, you just need to block the visible colors while leaving the UV light to pass through. try shining the green laser on orange plastic stuff
The quick and easy answer is, no, not really. PVC does surprisingly well when exposed to ultra violet rays (sunlight). Research shows little to no effect on PVC's tensile strength or elasticity after prolonged sun exposure. The only degradation that seems to occur is impact strength. That means the pipe may become slightly more brittle after
Importance Ultraviolet A (UV-A) light is associated with the risks of cataract and skin cancer. Objective To assess the level of UV-A light protection in the front windshields and side windows of automobiles. Design In this cross-sectional study, 29 automobiles from 15 automobile manufacturers were analyzed. The outside ambient UV-A radiation
It is mentioned that infrared light is not special in this regard and its ability to pass through glass is dependent on the make-up of the glass and the power of the source. The conversation also mentions possible reasons for the failure of infrared light to pass through glass, such as absorption from impurities or an antireflection coating on
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.
thickness. For instance, when light passes through a 1/4” thick sheet it will pass through twice as much pigment as when it passes through an 1/8” thick sheet. Therefore, the 1/4” thick sheet transmits less light than the 1/8” inch thick sheet. Graph 3: Light Transmission vs. Thickness of ACRYLITE
Edit In answer to the comment, you should be aware that no matter how transparent is the material in infrared, by absorbing the visible part of the radiation produced by the lamp it will still get hot. So your condition, transparent in IR, absorbant in visible, is not sufficient for your application if you want to avoid the shade getting hot
Answer: It is true: ultraviolet (UV) light — a culprit behind sunburns, wrinkles and skin cancer — does offer benefits for some skin conditions. In a medical setting, the same ultraviolet light that's emitted from the sun can be carefully used as therapy for certain hard-to-treat skin problems and other medical conditions. The main forms of
