That is a good question ! We haven't tried using glass instead of acrylic for our transilluminator. However, you could certainly put your gel onto a small glass plate over the clear acrylic when you are cutting gels to protect the acrylic. You can look for small glass plates online e.g. McMaster-Carr and other stores. We will also have a look at finding some glass plates to recommend with our different transilluminator sizes.
If you would like a replacement for your scratched clear acrylic surface, we can send you one, no problem, just let us know and we will happily help with that !
