UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and materials. UV curing is a low-temperature, high speed, and solventless process as curing occurs via polymerization. [2] Originally introduced in the 1960s, this technology has streamlined and increased automation in many ...
The dental LED curing lights use LED’s that produce a narrow spectrum of blue light in the 400–500 nm range (with a peak wavelength of about 460 nm), which is the useful energy range for activating the CPQ molecule most commonly used to initiate the photo-polymerization of dental monomers."
The main advantages of excimer lamps over other sources of UV and VUV radiation are as follows: high average specific power of UV radiation (up to 1 Watt per cubic centimeter of active medium); high energy of an emitted photon (from 3.5 to 11.5 eV); quasimonochromatic radiation with the spectral full-width at half maximum from 2 to 15 nm;
UV LED Nail Lamp. Featuring a near-perfect rating on Amazon and over 49,000 customer reviews, this best-selling nail lamp uses a built-in sensor and adjustable timer to cut down on drying time.
A blacklight, also called a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave ultraviolet light and very little visible light. [ 1 ] [ 2 ] [ 3 ] One type of lamp has a violet filter material, either on the bulb or in a separate glass filter in the lamp housing, which blocks most visible light and allows through UV ...
In the 1960s, visible light was used for the production of integrated circuits, with wavelengths as small as 435 nm (mercury "g line"). Later, ultraviolet (UV) light was used, at first with a wavelength of 365 nm (mercury "i line"), then with excimer wavelengths, first of 248 nm (krypton fluoride laser), then 193 nm (argon fluoride laser), which was called deep UV.
These lamps are used for fluorescence effects where less visible light is ideal. 09 N/A Sun-tanning lamps: These lamps produce wide or narrow band UV-B radiation 10 BL Black-Light lamps: Black light lamps give off long-wave UV-A radiation of around 350-400 nm. They are often used to attract insects to traps.
UV radiation at 185 nm is used to generate ozone. The UV lamps for water treatment consist of specialized low-pressure mercury-vapor lamps that produce ultraviolet radiation at 254 nm, or medium-pressure UV lamps that produce a polychromatic output from 200 nm to visible and infrared energy. The UV lamp never contacts the water; it is either ...
