I’m very happy with my new camera adapters, exactly what I needed. These perfectly suit my microscope and my new 2/3’’ camera. The optical elements of 0.63 adapter are very clean, unlike the adapters from other suppliers. For example the 0.5X adapter for my previous microscope (bought from a well-known company) contained dust particles inside, compelling me to dismantle it and spend a lot of time for cleaning the inner lenses. I would like to express my highest gratitude to your managers for their advertency and careful support. It was especially nice considering that mine was a very minor order. I wish prosperity and well being to BoliOptics team!
