The UVA, UVB, and UVC bands can be further divided into subtypes that denote specific applications and identify the principal absorber of the radiation. In addition to type, the Engineering360 SpecSearch database allows industrial buyers to search for UV light systems by configuration, application, specifications, and features. Curing chambers are used for the curing or hardening of "dry" inks, coatings, and adhesives. UV conveyors or continuous systems consist of a belt conveying unit, power supply and UV light source, as well as an enclosure that is open on both ends, which allows products or sheets to pass through the system.
Hand held or portable UV devices are useful for repair and testing in field, laboratory, plant floor, and other settings where transportation of large systems is impractical.
Spot or wand systems are benchtop units that provide a UV beam with a small spot size for selective curing applications. Wallorceiling-mounted UV systems disinfect anair stream as UV light irradiates theair circulating through the room. Counterfeit detection, surgery suites sterilization, room disinfector, forensics, water purifier, material processing and identification, dentist procedures. Fast curing of UV adhesives, coatings, and inks, industrial applications including UV bonding, sealing, and encapsulating, automotive, electronic, optical, and medical device assembly industries. Curing of inks, adhesives, varnishes, coatings and electronic potting resins: Certain inks, coatings and adhesives are formulated with photoinitiators and resins, which polymerize when exposed to the correct energy and irradiance. Security: Sensitive documents such as credit cards, driver's licenses and passports may include a UV watermark. Biology and Chemistry: Fluorescent dyes are used in biochemistry and forensics as genetic markers for research. Air and water purification: UV light is an effective tool used to change irritating pathogens, pollens, and mold spores into inert byproducts by destroying their DNA and breaking down the organic material found in indoor air. Analyzing and Authentication: Minerals, gems, art work, collectibles, and currency can be analyzed and authenticated using UV lamps due to their fluorescent properties.
Sanitary compliance and sterilization: The DNA of microorganisms can be altered when exposed to UV radiation. Solar Cell Testing: Research is underway on converting UV radiation from the sun into energy and can be used as substitute for conventional window glass. Filters can be integrated or optional and are used in analyzing and authentication applications. Multi-direction exposure UV systems can expose a product or material to light from multiple directions. Pulsed UV light systems and products that use light emitting diodes (LEDs) as a light source. UV curing systems use ultraviolet radiation to initiate reactions and cure adhesives, coatings and other UV curable resin products.

It is a form of electromagnetic radiation with a wavelength shorter (100 - 400 nanometers) than that of visible light (400- 780nanometers), meaning that UV light is more energetic. Excitation occurs when radiation is excited by the motion of the atoms or molecules, or causes an electron to jump from an occupied orbital into an empty, higher-energy orbital. Ionizing radiation is used for X-rays, medical, biological and sterilization applications and is a by-product of nuclear power.
The following chart provides an abridged view of the electromagnetic spectrum and divides UV light into these spectral subcategories.
Also known as black light, UVA rays comprise 98% of the ultraviolet in sunlight at the Earth's surface. UVC rays have the highest energy per photon, and thus are more dangerous than UVA and UVB radiation.
They consist of a power supply, light source, and enclosure or chamber that provides a work surface and shields the operator from radiation. Process or line-mounted UV systems include a power supply, light source and flange, cartridge mounting or fitting, web system, coating line, and conveyor lines or tanks that transport chemicals, plastic film, or other transparent media for processing. Currencies for many countries also include an image and multicolored fibers that are visible under ultraviolet light. Papyruses and manuscripts can be read using UV light to distinguish ink from paper on the surface. Phototherapy is a treatment available for skin conditions like psoriasis and eczema, as well as vitamin D deficiency and certain fungal growths.
The light causes chemical reactions to occur in the photoresist material to create a pattern on a sample.
When used in conjunction with other sterilization techniques, UV light is an effective tool to sterilize laboratory workbenches and medical facilities. Shortwave bulbs emphasize UVB and UVC while longwave bulbs are used from UVA and visible light.
Intensity decreases as the object's distance from the light increases and when curing through substrates that transmit less than 100% of the light used for curing. This is important if the bond-to material is not transparent and shadows the adhesive from an overhead beam. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

They rays are completely absorbed by the ozone layer, but can pose a serious threat if looked at for an extended period of time.
They prevent the cured item from being exposed to dust and contaminates in the air during drying.
The reaction is very fast and is used in glass and plastic bonding, optical fiber coatings, dental fillings and finger nail gels. UV lamps are also used to detect organic mineral and biological deposits that remain on surfaces, such as restrooms and bedding.

As the following diagram shows, the energy of the wave increases as the wavelengths become shorter. The loss of an electron can change the chemical structure and cause cell damage by mutating its genetic code. UVA can cause damage to collagen by destroying vitamin A and causing damage to keratinocytes. They damage the skin's superficial epidermis layers and play a key role in the development of skin cancer. UV curing has been shown to increase production speed, reduce reject rates, improve scratch and solvent resistance, and facilitate superior bonding. UV traps can also be used to eliminate small flying insects that are attracted to the light. In modern society, we have the luxury of air heaters and air conditioners for every shape and size room, house, vehicle or tent. Despite its link to skin cancer, UVA rays are frequently used in tanning booths and sun lamps. Cool or heat your indoor or outdoor space with portable Air Conditioners and Heaters from Mobile Air.
