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.
