For oil immersion microscopy, I understand that the oil is required to increase the numerical aperture, and thus the resolution, of the lens. I have tried looking into these microscopes and the only method I have seen of applying the oil is to place a dot of it on the lens and then lower the lens into the specimen. However, what if the lens and specimen are moving relative to each other? Wouldn't you need an oil layer of constant thickness? Also, when imaging very thin layers, wouldn't the oil be heated significantly by the light from the microscope?
Basically, my question is whether one would need to install an oil distribution system to prevent overheating of the oil and to ensure that an even layer is coating the lens. Do you know if this has been researched? I cannot find information on it anywhere!
I figure that the oil would have to be introduced in a laminar flow onto the coverslip but I'm just unsure if this is actually necessary. I would be dealing with nanoparticles, but none of which are living. Thanks for your help in advance!
