Today for sale we have an interesting kit by Gamma (Hungary). This is so called Goerz condenser with attachments to use it for dark/light field phase contrast microscopy, but with benefit of better resolving of lesser details.
Genuine screw on focusing tube is missing, replaced with makeshift one. One of numerical attachments has delamination, another one has very small crack on the edge. However, this kit was inspected by a microscope technician who confirmed that it still can be used, since there are no issues with aperture, shift mechanism, and other optical components and neither delamination/cracks affect image quality. Kit also includes 3 color glass inserts for the condenser. The dark blue (almost violet), yellow and orange ones.As we guess, these are for UV/Fluorescent microscopy purposes, but we have no more idea on that.
