This type of microphone uses piezoelectric materials to transform vibrations into electrical signals. Early mics used Rochelle salt due to its impressive output, but it was somewhat fragile and sensitive to moisture. Later devices used ceramic materials such as lead zirconate and barium titanate. They...
Microscopes are used both in classrooms and in making important evaluations in medical laboratories and other microtechnologies. The different types are designed for these different uses, and therefore will vary based on their resolution, magnification, depth of field, field of view, illumination ...

There are several different types of microscopes used in light microscopy, and the four most popular types are Compound, Stereo, Digital and the Pocket or handheld microscopes. Some types are best suited for biological applications, where others are best for classroom or personal hobby use....
Hence, it is vital to know about the different types of microscopy depending on the field of interest to use. In this chapter, we review the characteristics of the main microscopes. We focus on the types of emitting light sources, such as incandescent lamps, laser light, arc or flash ...
two different types of stereo microscopes—fixed and zoom—still offer variations in the magnification and whether one can alter it. Often, stereo microscopes have lower power than compound microscopes. Whether they have fixed or zoom magnification, they are generally below 100x magnification. There ...
Different industries now rely on scientists to collect and analyze data to fuel their growth. There are various types of scientists working in distinct fields. Below, we’ve explained the job profiles and the kind of work these scientists do. ...
These lab doctors identify the causes of diseases by examining body tissues and fluids under microscopes. Pediatricians They care for children from birth to young adulthood. Some pediatricians specialize in pre-teens andteens,child abuse, or children's developmental issues. ...
The first type includes widefield (WF) microscopy, which is based on Köhler illumination that involves constant excitation of dyes in a specimen during image acquisition. Conventional WF microscopes are equipped with an arc lamp, whereas recent models use a light-emitting diode (LED) lamp. The...
