Electronic circuit, the transformer is 28mm (1.1") high.
The red squares in the background are spaced 1mm apart.
Whereas normal microscopes often have just a paper thin depth of field, we can demonstrate up to 1.2" (30mm) depth of field along with a unique lighting system to allow for shadow free imaging even with high samples. In this image we show an electronic circuit with a height of 28mm (1.1"). As can be seen, the entire circuit is fully resolved
