Understanding UVC Wavelengths
UVC LEDs operate between 200nm and 280nm, but each wavelength has unique characteristics.
230nm UVC LED (Far-UVC)
- Lower penetration into human skin
- Potential for safer exposure
- Emerging applications
265nm UVC LED
- Peak DNA absorption
- Highest sterilization efficiency
- Common in medical systems
280nm UVC LED
- Higher output power
- Longer lifetime
- Widely used in industrial systems
How to Choose the Right Wavelength
Selection depends on:
- Target microorganisms
- Application environment
- System design
