SUMMARY

The discussion centers on determining the UV-C transparency of glass from flatbed scanners, specifically in the 250-280nm range. The user is constructing a DIY UV-C germicidal box and is uncertain if the glass is borosilicate. Participants suggest practical testing methods, such as using a dayglow jacket to observe UV effects under sunlight, while also cautioning about UV exposure risks.

PREREQUISITES
  • Understanding of UV-C light properties and its germicidal applications
  • Familiarity with optical properties of glass materials
  • Basic knowledge of DIY electronics and safety precautions
  • Experience with practical testing methods for material properties
NEXT STEPS
  • Research the optical properties of borosilicate glass versus standard glass
  • Learn about UV-C light sources and their applications in germicidal technology
  • Explore safe testing methods for determining material transparency to UV light
  • Investigate the effects of UV exposure on various materials and safety measures
USEFUL FOR

This discussion is beneficial for DIY enthusiasts, safety engineers, and individuals interested in UV-C technology for disinfection purposes.

Glass in flatbed scanner transparent to UV-C (~254nm)?
Hello,

I am making a DIY UV-C germicidal box as part of my defense-in-depth strategy for protecting my household but I am having trouble determining whether a particular plate of glass that I have will be transparent to UV in the 250-280nm range. The glass in question is from a flatbed scanner and I'm hoping it is borosilicate but I don't know how to test without ruining it.

Does anyone know how I could determine the type (and optical properties) of glass used in common flatbed image scanners?

Thanks

I wouldn't expect it to be anything other than normal glass

Do a practical test and find out
 
Get a dayglow jacket and see how it looks under your glass in sunlight.
PS mind the UV stuff. It can harm your eyes.
