Overview of the 10 best types of microscopes

10 best types of microscopes Visitors: 231

 

The microscope is not only a professional device, but also a way to attract children and teenagers to science. There are certain differences in the rich range of devices.

The design consists of a tube - a hollow tube, where the eyepiece (lens system) is equipped. When it is removed, the magnification is adjusted. The device is equipped with attachments for one (monocular) or two eyes (binocular) or a double lens with a camera for shooting.

The lens is positioned in front of the object in question. It can be of two types: dry and immersion. The increase is carried out by a special mechanism – a revolver nozzle (expensive models). Simple models require manual lens changes.

The element under study is placed on the slide table. To move the object vertically, use the adjustment screw. The illumination is adjusted by a capacitor. Some models are equipped with lighting (electric or mirror). Operating principle:

The object under study is placed on a slide, covered with a thin glass plate on top.

The light is concentrated by a third lens system – a capacitor, which is attached by a holder. Below is a lighting mirror that transmits the light from the lamp.

The image is saved if the microscope is equipped with a camera.

The principle of operation of an electron microscope is based on the image of a beam of charged energy particles. They are controlled by magnetic lenses that set the motion of the electrons.

One part is scattered, the second part passes through the object. The information comes from the charges and is fed to the screen. Purpose and functions.

 

The main purpose is to obtain enlarged images, measuring objects visible or invisible to the eye.

 

Main tasks:

 

Edit schemas.

Defect analysis.

Monitoring.

Preparation of materials.

Testing.

Removing micro-characteristics.

The scope of application of microscopes is immeasurably wide: metrology, cryobiology, toxicology, virology, nanometrology, chemistry, biology, forensic examination.

 

Functions of microscopes

 

Creating a light stream.

Reproduces the magnification of the optical image.

Image visualization.

 

Important parameters:

 

Type of construction

 

The material of manufacture of the device indicates the reliability and durability of the product. The best characteristics are distinguished by a metal alloy. Its structure reduces vibration, and there are no fluctuations during temperature changes.

 

The plastic case is inferior to the metal one in strength.

 

Optics

 

The most important parameter is the arrangement of a high-quality focus.

 

Standard lenses are considered DIN or JIN. These models are available in retail, they are easy to replace in case of breakage.

 

The lenses give light correction.

The more of them, the better the colors are transmitted, especially at long distances. Plastic versions, which are equipped with children's microscopes, give a fuzzy and blurry image.

 

Eyepieces

 

Lenses located closer to the eye. They are characterized by a wide field of view, which gives a larger image. It is easier for the eyes to focus on the object. The minimum allowable diameter of the eyepiece lenses is 18 mm.

Backlighting

 

Incandescent lamp. The simplest and most inexpensive.

Fluorescent lighting. A glass flask filled with gas. The cost is more expensive, but it works longer.

LED lamps. They are professional devices, economical, and efficient.

Halogen lamps. A powerful stream of white light ensures bright lighting in all conditions.

Stunt

 

Coarse focusing consists of a single knob that moves the subject through the focal plane of the lens. To see the image, the control is rotated, but it is difficult to do this.

 

With precise focus, the object is magnified in the vertical and horizontal plane.Secondary parameters:

 

Replaceable eyepieces. The mechanism is replaced quickly, which limits the ingress of dust, since it is difficult to clean these places.

A set for experiments. If the complete set includes ready-made samples, then you can start working immediately after purchasing the microscope. This is convenient, but does not play a role in choosing the right device.

Digital screen. Such a device is suitable as a way to demonstrate the process, since the actions are visible on the display. But the cost increases significantly, almost all models are connected to external monitors. What should be a good microscope:

 

An important requirement for a high – quality product is a binocular or trinocular nozzle. Two eyepieces allow you to look with two eyes, do not exert a load on the eyes during prolonged operation.

 

The trinocular mechanism includes an additional tube for mounting the camera, so surveillance, photo or video shooting is carried out simultaneously.
