The microscope is an instrument that allows observing elements or structures that can not be observed at the naked eye, through lenses, viewers and light rays, which bring or enlarge the image on scales suitable for examination and subsequent analysis. He was invented by the Dutch Zaccharias Janssen in the sixteenth century.

Microscopes for field

For field observation work we can have portable microscopes, either in your presentation as analog or digital models.

Analog microscopes or also pocket calls

They have a maximum and increase to 100x, so they are useful to see details in fungi and smaller parts of moss, lichens and flowers.

Digital microscopes

They reach goals up to 220x, which can study mites, they are very useful in the sectors in charge of textile, domestic or housing control.

Microscopes for laboratory

Stereoscopic microscope

It makes possible the three-dimensional vision of the objects, and to achieve it uses two eyepieces (those that are close to the eye) and two objectives (those found near the sample). It is used for relatively large objects, so it requires small increases, generally 4x and 40x to 60x.

Luminous field composite microscope

It is the most common microscope. It is used to increase images of objects that are not visible to the naked eye. In the optical microscope the sample is illuminated by visible light. This means that there is a light focus pointing towards the sample. That same light is conducted through the objective and of the eyepiece to form the image in the eye of the observer.

Dark field microscope

In this microscope the light rays do not penetrate directly into the object, but it is illuminated obliquely, in this way the illuminated object disperses the light and is made visible against the dark background. It is used to analyze transparent and non-pigment biological elements, impossible to see with natural light. To achieve this, the team has a condenser that illuminates the object with an intense light, but indirectly.

Polarized light microscope

also known as petrographic microscope. This microscope is actually a type of optical microscope to which two polarizers have been added. This means that the light wave used to observe the sample has a specific oscillation direction. It is very useful for observing crystal structures of rocks and minerals.

Inverted microscope

It has an inverse arrangement in its components with respect to a conventional microscope. The light and the condenser are looking down and found on the platform, and the goals are below pointing up. This equipment allows observing organisms or fabrics in culture without prior preparation.
