Glass slide with micrometric ruler. 1 mm divided in 100 units (0.01 mm/division).
This particular microscope slide provides a size reference for your samples.
This is the last generation of the Blips Labkit.
With the most powerful lens (Ultra), you can use your phone like a digital microscope: with resolution of 3-4 micron you can see living micro-organisms, or even blood cells on prepared slide. With the extra-thin Macro lens kit (inside the box) you will get powerful lenses to keep always with you, for seeing microscopic details whenever you want.
