I'd like to purchase additional welding googles for use while coating
specimens in our new vacuum evaporator (via thermal evaporation using
sharpened carbon rods). I have one old pair of welding googles, but I
have no idea what shade they are (they don't appear to be labelled).
Does anyone know the minimum shade value for this purpose? 5? 10?
15? Something in-between? I and other researchers in the lab enjoy
seeing, so I'd like to choose the right shade.
