1. Stereo Microscope: A stereo microscope is a type of microscope that uses two separate optical paths to provide a three-dimensional image of the specimen. It is commonly used for inspecting fibers and other small objects.

2. Polarizing Microscope: A polarizing microscope is a type of microscope that uses polarized light to examine the structure of fibers. It is used to detect defects in fibers, such as breaks, knots, and other irregularities.

3. Reflected Light Microscope: A reflected light microscope is a type of microscope that uses a light source to illuminate the specimen from the side. It is used to examine the surface of fibers and other objects.

4. Fluorescence Microscope: A fluorescence microscope is a type of microscope that uses a special light source to excite fluorescent molecules in the specimen. It is used to detect the presence of certain chemicals in fibers and other objects.

5. Scanning Electron Microscope: A scanning electron microscope is a type of microscope that uses a focused beam of electrons to examine the surface of fibers and other objects. It is used to detect defects in fibers, such as breaks, knots, and other irregularities.
