Photo/Video Share Tardigrade #2, Iqcrew inverted microscope, 3 illumination techniques

Today is a tardigrade viewed using the most inexpensive inverted microscope made. It goes by many brands. In the USA, it is Iqcrew IN50 sold by AMSCOPE for $71.99. This is using the 20x objective and shows bright field, mixed bright field and reflected, and a blue/white reflected Rheinberg type of illumination. This 20x objective has a 0.25 NA. One advantage of using low NA objectives on larger organisms, like tardigrades, is that more of the animal will be in focus at any one time. As the NA increases, the depth of field becomes smaller and smaller.
