Ultraviolet light

New research may finally be answering the question of why scorpions glow in ultraviolet light, like that emitted by black lights and the moon.

The key to understanding biology is a solid foundation in its most basic concepts. These resources will introduce you to basic biology principles so you can move on to more complex topics.

Albert Einstein's stimulated emission theory has been validated by large amounts of light, but never before by individual photons—until now.

You can make tons of things glow in the dark using a black light or ultraviolet lamp. Discover 15 science projects that you can attempt.

This is the definition of ultraviolet radiation or UV light, with a look at its wavelength range and uses.

In this landscape photography tutorial, learn how to use ultraviolet-induced visible fluorescence to create otherworldly images.

Why Blue Light Is So Bad: The Science And Some Solutions. "Children under the age of 14 who use tablets and phones with high energy light are at special risk. Until 14 their corneas arent fully developed and lack the protection of adult eyes "

Don Komarechka posted a photo: This image of Scilla flowers (Scilla siberica) is shot with UV fluorescence: the subject is covered in ultraviolet light but the camera only detects visible light reflecting off the surface. If the UV light is transformed through fluorescence into light we can see and the camera can capture, we get an image! While many flowers don’t directly reflect UV light, that doesn’t mean they absorb it entirely. Pollen, for example, is a common element in many flower…

Ultraviolet photography is an interesting photographic method of capturing images by using light from the ultraviolet spectrum.

Well, some people wonder what could be done with Nichia based NC4U133 (365nm) / NC4U134 (385nm) systems and my High Power UV LED Radiation System with easily exchangeable radiation heads for nominal wavelength of 365nm, 385nm, 395nm, 400nm and 405nm using the most modern 40W UV LEDs or the simple and now quite common 365nm Nichia flashlights which use the single dice NCSU033A and NCSU033B chips. Well, here it is without much ado... [click on image to see a larger one] White Zinnia in visible…
