  2. Deuterium arc lamp - Wikipedia

    en.wikipedia.org/wiki/Deuterium_arc_lamp

    Deuterium is used rather than normal hydrogen because of its greater intensity of UV emission in the molecular band. A deuterium lamp uses a tungsten filament and anode placed on opposite sides of a nickel box structure designed to produce the best output spectrum. Unlike an incandescent bulb, the filament is not the source of light in ...

  3. Fluorescent lamp - Wikipedia

    en.wikipedia.org/wiki/Fluorescent_lamp

    The spectrum of light emitted from a fluorescent lamp is the combination of light directly emitted by the mercury vapor, and light emitted by the phosphorescent coating. The spectral lines from the mercury emission and the phosphorescence effect give a combined spectral distribution of light that is different from those produced by incandescent ...

  4. Blacklight - Wikipedia

    en.wikipedia.org/wiki/Blacklight

    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 ...

  5. Mercury-vapor lamp - Wikipedia

    en.wikipedia.org/wiki/Mercury-vapor_lamp

    Low-pressure Hg lamps can be rather small, but efficient sources of deep UV light. Low-pressure mercury-vapor lamps [16] usually have a quartz bulb in order to allow the transmission of short wavelength light. If synthetic quartz is used, then the transparency of the quartz is increased further and an emission line at 185 nm is observed also.

  6. Photo-oxidation of polymers - Wikipedia

    en.wikipedia.org/wiki/Photo-oxidation_of_polymers

    Depending upon substitution, the UV absorption spectrum is changed to match the application. Concentrations normally range from 0.05% to 2%, with some applications up to 5%. Frequently, glass can be a better alternative to polymers when it comes to UV degradation. Most of the commonly used glass types are highly resistant to UV radiation ...

  7. Tanning lamp - Wikipedia

    en.wikipedia.org/wiki/Tanning_lamp

    Tanning lamps (sometimes called tanning bulbs in the United States or tanning tubes in Europe) are the part of a tanning bed, booth or other tanning device which produces ultraviolet light used for indoor tanning. There are hundreds of different kinds of tanning lamps most of which can be classified in two basic groups: low pressure and high ...

  8. Xenon arc lamp - Wikipedia

    en.wikipedia.org/wiki/Xenon_arc_lamp

    This spectral region can contain about 10% of the total emitted light. [citation needed] Light intensity ranges from 20,000 to 500,000 cd/cm 2. An example is the "XBO lamp", which is an OSRAM trade name for a pure xenon short-arc lamp. [11] For some applications, such as endoscopy and dental technology, light guide systems are included.

  9. Metal-halide lamp - Wikipedia

    en.wikipedia.org/wiki/Metal-halide_lamp

    Some bulbs have a phosphor coating on the inner side of the outer bulb to improve the spectrum and diffuse the light. In the mid-1980s a new type of metal-halide lamp was developed, which, instead of a quartz (fused silica) arc tube as used in mercury vapor lamps and previous metal-halide lamp designs, use a sintered alumina arc tube similar to ...
