Ultraviolet (UV) light is a component of the electromagnetic spectrum that falls in the region between visible light and X‐ Rays.
This invisible radiation includes the wavelength range of 100 nm to 400 nm.
It can be categorized into four separate regions:
100 nm to 200 nm: Far UV or vacuum UV (these wavelengths only propagate in a vacuum)
200 nm to 280 nm: UVC – useful for disinfection and sensing
280 nm to 315 nm: UVB – useful for curing, and medical applications
315 nm to 400 nm: UVA (or “near UV”) – useful for printing, curing, lithography, sensing & medical applications
The working mechanism of LIVA book sterilizer uses UVC (253.7nm) to sterilize the pathogenic microorganisms like viruses, bacteria and allergens on the books. The sterilization rate can achieve above 99.9% within only 60 seconds.
