Excimer Lamp Application And Uses

The term Excimer lamp refers to ultraviolet lamps that are specially designed to emit UV radiation in the wavelength range of 170 nm to approximately 230 nm. The wavelength emission depends on the noble gas excimers present in the lamp. Excimer lamps are popular for generating far UVC, typically in the specific range of 222 nm, an ideal range for UV disinfection, although they are capable of producing other ranges for use in applications. 

Excimer lamps designed to emit UV radiation in the range of 172 nm are commonly used for UV curing applications and when designed to emit 185 nm, are known to create ozone.

Excimer Lamps at 222 nm for Sterilization

Conventional UVC germicidal lamps typically emit radiation in the range of 254 nm, which is highly effective for germicidal applications, although is unsafe for use in the presence of humans. Far UVC at 222 nm is proven just as effective, if not more than 254 nm in some germicidal applications and offers the benefit of safe usage in occupied spaces. 222 nm Excimer lamps are proven just as effective at eliminating threats of stubborn viruses such as methicillin-resistant Staphylococcus aureus (MRSA) and other antibiotic-resistant pathogens.

UV Surface Activation at 172 nm with Excimer lamps 

UV Excimer lamps designed to emit 172 nm radiation are used primarily for UV curing and surface activation industrial applications. Ultraviolet radiation at 172 nm alters surface energy to allow for improved adhesion of coatings to substrates. UV lamps at 172 nm deliver electromagnetic energy to alter organic molecule bonds to improve adhesion and UV curing applications without altering physical surface properties. 

Excimer Lamps for Ozone Production at 185 nm

Ultraviolet lamps designed to emit UV radiation in the range of 185 nm are known to produce ozone and effective oxidizer and deodorizer. Ozone lamps are commonly used in water and air sterilization systems to purify the air and eliminate the threat of airborne diseases while also removing foul odors.

UVB Phototherapy Lamps for Vitiligo

Vitiligo is an autoimmune disorder which causes white patches to appear on the skin due to a progressive loss of melanocytes, melanin forming cells. These colorless patches on the skin have distinct margins, are non-scaly, and typically will get larger over time. They may also appear inside of the nose and mouth, and loss of color can also affect hair and facial hair.

UVB Lamps for Vitiligo Provide Successful Treatment

Ultraviolet, UV lamps designed to emit narrow band UVB give patients hope for a positive prognosis when properly administered. UVB lamps for vitiligo are considered safe under the proper direction and are typically administered in the office of a dermatologist. Ultraviolet lamps are most effective at restoring skin pigmentation on patients with vitiligo on the neck and face; white patches on fingertips, toes, and the lips are less responsive to UVB phototherapy.

Narrowband UVB Proven Effective Treatment for Vitiligo

Narrowband UVB lamps were shown to provide nearly 75% repigmentation on 63% of patients receiving phototherapy for vitiligo twice per week over the course of one year in this study published by the National Library of medicine. Narrowband UVB lamps were shown to be more effective than another popular treatment with UVA lamps and Psoralen medication, referred to as PUVA. Patients should speak with their doctor to determine the best course of action for their type of vitiligo.
