Need source of small quantity of optical gel

So, I am getting closer to finishing the Muon Sensor Project I have been working on and need one more item. Apparently this sensor will work much better if I put a small quantity of something called optical gel between the silicon photo multiplier and the plastic scintillator material. I only need a few grams and all I have been able to find is sold in MUCH larger quantities.

Anyone know/have a source for a few grams I could purchase?

Walter - is this what you need? Coupling gel for fiber optics, etc.

Be careful with those muons. You’re no Geordi Laforge. :slight_smile:
