Microscopes for dermatology: how to choose the best equipment for diagnosing skin diseases

Types of microscopes used in dermatology

The standard structure of a microscope includes an eyepiece, an objective lens, a condenser, a slide, and a mirror. The objective lens is one of the main components, responsible for magnifying the objects under study. The degree of magnification depends on the number of lenses. Microscopes are classified based on their design into the following categories:

1. Straight — designed for small specimens as well as specimens on slides, the object of study is placed under the objective lens.

2. Inverted — involves placing the object of study above the objective lens, used for samples in special dishes.

3. Stereomicroscopes — provide a three-dimensional image of the objects under the lens.

4. Digital — models of special design, equipped with a digital camera instead of a tube.

5. Confocal — designed for highly complex biological studies.

6. Electron microscopes — use a stream of electrons instead of light.

7. X-ray microscopes — used to study especially small samples.

Dermatologists actively use dermatoscope — a special device for the diagnosis of skin diseases, the study of various formations, pigment spots, moles, papillomas. Devices are divided into two main types: optical and digital. Optical are represented by traditional models that work by magnification through a lens to visualize the skin without digital technology.

A digital dermatoscope is an advanced modern device that is equipped with a camera and allows you to save images. The images obtained are important for later analysis and archiving.

Dermatoscopy is performed by contact and non-contact methods. Contact method is based on touching the dermatoscope to the skin, which provides a detailed image. Non-contact is performed without touching, which makes the device convenient for quick examination and hygienic.

Trichoscope is a professional scalp and hair condition analyzer. Most devices are mobile, equipped with a video camera, moisture sensor, elasticity, greasiness sensor. A special microscope allows you to learn the thickness of hair, growth phase, skin features, identify, problems and diseases.

Key characteristics of microscopes for dermatology

Microscopes in dermatology are designed for the study of biological samples. The device is designed to study cells, tissues, microorganisms. The main features of the equipment:

1. High magnifying power. Lenses of microscopes are able to magnify the sample in 40, 1000 and more times for detailed study.

2. Sophisticated optics. The combination of lenses and glasses provides a high level of clarity and magnification.

3. Illumination. Built-in, dimmable illumination system provides the necessary illumination of the specimen being examined.

4. Wide field of view for high quality images of the objects under study.

5. Convenient slide table for comfortable work of a specialist.

Depending on the number of eyepieces, microscopes are monocular, binocular, trinocular. Trinocular models allow you to connect a camera for filming. Modern models of equipment are characterized by versatility and high quality elements of the device.

Additional functions and accessories

Microscopes can be used for contrast microscopy methods, such as luminescence and phase-contrast microscopy. Luminescence microscopy relies on staining with fluorochromes, which emit radiation when exposed to UV light. Phase-contrast microscopy is based on the difference in wavelength between rays that have passed through the object. High-quality equipment with contrast microscopy capabilities significantly enhances the accuracy of research. To operate optical equipment, specialists use additional accessories and devices, including:

• halogen, LED lamps;

• additional lenses;

• wide-field eyepieces;

• light filters;

• screens for displaying research data;

• mirrors.

Accessories for microscopes are recommended to be selected according to the technical characteristics and model of the device. Even in the simplest situations, when the diagnosis is obvious, it is necessary to conduct microscopy of the affected skin with the use of multifunctional models of equipment. In combination with laboratory diagnostics, the doctor can easily find out the type of pathogen and its resistance to certain drugs.

Polarizing filter in the microscope facilitates the work of a specialist in case of excessive glare. With the help of a special program, you can eliminate small noise and improve the quality of images.

How to choose a microscope for dermatology?

Regardless of their specialization, a dermatologist requires a microscope. Examining the skin and its appendages helps identify skin diseases and establish a definitive diagnosis. The process of determining the cause of a pathology includes several stages: visual inspection, and collecting material for histological or microbiological analysis. Not all microscopes have the same functions and design, so before purchasing a microscope, it is important to consider several factors:

1. Magnification range. The magnification capabilities of the instrument should match the complexity and size of the samples.

2. Resolution. The criterion determines the smallest detail that can be discerned. Lenses with high magnification, sensitive light receivers, advanced image processing algorithms contribute to improved resolution.

3. Lighting. The device should provide uniform illumination, accurate transmission of shades.

4. Ergonomics. The simplicity or complexity of setting parameters for observing the sample affects the comfort of using the microscope.

Modern models of devices allow you to control the settings through a touch screen or mouse. In most cases, the system automatically adjusts the optimal parameters for research.

Tips for using and caring for the microscope

In order to maintain stable operation of the microscope, it is recommended to carry out regular inspection as well as maintenance of the device. A long service life of the device guarantees compliance with the basic rules of operation:

1. Placement on a firm, level surface.

2. Placement of the microscope in a cool, dry place to prevent corrosion, mold formation, fungal growth.

3. Using a cover after each use of the device to protect it from dust.

4. Treatment of moving metal parts with special silicone grease 1-2 times a year.

5. Regular care of the optical system.

Maintenance of the microscope is aimed at preventing dust, moisture, heat exposure, corrosion development. Before cleaning lenses and parts, you should familiarize yourself with the recommendations of the manufacturer of a particular model of equipment.

Conclusion

Dermatology is engaged in the treatment and prevention of skin diseases. Dermatologists use diagnostic, therapeutic, surgical medical equipment. Various devices are needed for proper diagnosis. First of all, dermatoscopes and trichoscopes are important, providing translation, fixation of images. The use of a microscope is required during laboratory diagnosis of samples taken from patients.

To provide high-quality care to patients in a dermatology institution, it is essential to be professionally equipped with medical devices. Reliable equipment, furniture, microscopes, and dermatoscopes can be purchased through the Bimedis marketplace from anywhere in the world. The wide selection of equipment comes from trusted manufacturers and sellers. For more information and expert advice, experienced site managers are available to assist you.
