280nm

280nm light falls within the UVC (ultraviolet C) spectrum, a range of electromagnetic radiation known for its high energy. This makes it particularly effective for certain applications but also necessitates careful handling due to its potential hazards.

Key Characteristics:

  • Wavelength: 280 nanometers
  • Type: Ultraviolet C radiation
  • Energy: High energy due to its short wavelength
  • Visibility: Invisible to the human eye

  • Sources for 280nm Light

    UVC lamps: These are specialized lamps designed to emit ultraviolet C radiation, including wavelengths around 280nm. They are commonly used for sterilization and disinfection purposes.

    UVC lasers: Lasers can produce highly focused beams of UVC radiation, which can be used for precise applications like micromachining and medical procedures.

  • Application of 280nm Light

    Germicidal irradiation: UVC light can effectively kill microorganisms, making it valuable for sterilization and disinfection purposes in healthcare, food processing, and water treatment.
     
    Analytical chemistry: 280nm light is often used in spectrophotometry for protein analysis, as proteins absorb strongly at this wavelength due to aromatic amino acids.

    Photolithography: In semiconductor manufacturing, UVC light is used to expose photoresist, a light-sensitive material, to create patterns for integrated circuits.
