RP Photonics Encyclopedia

For some applications, nonlinear crystals with a very small thickness of well below 1 mm are used. This may be necessary for minimizing the group velocity mismatch, e.g. in optical autocorrelators for extremely short pulses.. A common method for obtaining ultrathin crystals is to first optically contact a thicker nonlinear crystal with some substrate (e.g. of fused silica) and then to polish Get price

Additives Fillers

Additives, which protect composites by absorbing the UV, are called ultraviolet absorbers. Materials, which protect the polymer in some other manner, are known as ultraviolet stabilizers. In the event that a non-gel coated resin will be exposed to sunlight, the addition of a UV Get price

Light

Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye. It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun.Animals can also see light. The study of light, known as optics, is an important research area in modern physics.When light hits an opaque object it forms a shadow. Get price

Choosing sunglasses: Is UV protection important?

Yes, ultraviolet (UV) eye protection matters. UV radiation from the sun can damage not only the skin of your eyelid but also the cornea, lens and other parts of the eye. UV exposure also contributes to the development of certain types of cataracts, growths on the eye and possibly macular degeneration. Get price

electromagnetic spectrum

Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength.Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies. The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges, commonly Get price

Discover if UV Sun Rays Go Through Windows Here!

Tinted windows don't block all UV rays. If you have windows that claim to block UV rays, it is important to point out that a very tiny amount of UV still gets through. As I mentioned above, it's possible to block 99.9% of UV rays, but even if their windows are that good, the 0.1% can add up at Get price

Ultraviolet catastrophe

The ultraviolet catastrophe is the name given to a conflict between theory and the observation in classical physics.. An ideal black body at thermal equilibrium emits radiation in all frequency ranges. It emits more energy as the frequency increases. By calculating the total amount of radiated energy, it can be shown that a blackbody would release an infinite amount of energy. Get price
