Live Human Blood Cells (erythrocytes and leukocytes). A Neutrophil eating bacteria. DIC Microscopy

This video showing blood cells under the microscope i.e. red (erythrocytes) and white (neutrophils) cells. It also shows how a neutrophil "eats" bacteria (micrococci) - a process called phagocytosis.

Two setups of differential interference contrast (DIC) are tested: the old one with a cheap analyzer from ebay + a zeiss aplanatic/achromatic condenser (NA: 0.9), and the new one with original zeiss analyser + zeiss aplanatic/achromatic condenser (NA: 1.4 oil). I think the difference between the two setups is obvious. What do you think?

I do not mean to cover up lack of microscopy skills, but the image is much clearer when I look through the eyepiece, probably due to the camera...my next investment project. Any suggestions?

Microscope: Axioplan 1.
Objectives: Mostly Zeiss 63x/1.4 Plan-apochromat and Zeiss 100x/1.3 Plan-neofluar in the end.

Hi Microscopy! I left you a comment earlier, I did a lot of research about cameras and had trails and errors, the best advise I can give you is if you planning to use 100x objective as your primary weapon then go for full frame, here is my list of suspects: Panasonic S1H, Panasonic S1, Nikon Z6, Sony Alpha a7 III. Don't get 8k camera, I have tested it and almost no difference to 4K. If money is no object then go for full frame with best dynamic range. If you on budget, you can't beat Sony a6300 asp-c good luck!

Microscopy how do you get image of white cells in the process of phagocytosis?

Very nice video! May explain what you mean cheap analyzer and original analyzer slides?
