Petri dishes
Posted: Mon Feb 15, 2021 6:40 pm
Hello All,
Wondering if anyone could recommend a brand and source for decent glass 60mm petri dishes for use with an inverted. The cheap glass ones are obviously not meant for this. When held up to the light it is like looking through the bottom of a Coke bottle! I've had some success with the poly-carbonate dishes but they are a bit thin for the range of the correction collar on my LWD 40X. From what I understand they do not work as well with polarization either.
Cheers, Al.
