Microscope - uses and areas of application in laboratory
Microscopes are used mainly in laboratories in the fields of science, research development, industry and production. The microscope is an essential piece of laboratory equipment for biology medicine, chemistry or material science. For instance, our microscopes are used in industrial biological and medical laboratories to study tissue and cell cultures, urine blood, plasma smears, microorganisms, bacteria yeasts, fungi, mycoses or histological specimens. The fields of use of the existing microscopes by Kern & Sohn, Helmut Hund, A. Krüss Optronic or Levenhuk include hospitals medical practices, research institutions, universities, specialized colleges and schools. Our cost-effective microscopes are ideal for professional use in cell and microbiology, veterinary and human medicine, such as dermatology, urology, gynecology or pathology, and are also used for food and beverage processing in the food industry and breweries, as well as for the study of wastewater samples and slurry in treatment plants. Microscopes are also used for material analysis and for the analysis of work materials in industrial production. We're happy to help you find the most suitable microscope for your laboratory.

Microscopes - function and structure of a microscope
A microscope is an electronic instrument for the inspection and expansion of very small objects. Essentially, the microscopes consist of two optical components, the objective lens and the eyepiece. They are linked by a microscope tube to each other. The different microscopes vary depending on their design and field of use. In keeping with their design our online shop classifies laboratory microscopes into upright and inverted forms.
Essentially, the configuration of the modern microscope usually consists of the following microscope components:
Microscope types: our collection currently includes stereomicroscopes and monocular microscopes, binocular microscopes and trinocular microscopes. A stereomicroscope always has two eyepieces, like any binocular microscope, where two objective lenses are created concurrently in a stereomicroscope, representing the target at different viewing angles, which ultimately results in a stereo effect. The third eyepiece is typically used in a trinocular microscope with an extra vertically expanding lens line to mount the camera.
Microscope objectives: Many of the properties of the microscope picture depend on the chosen microscope objective. These are generally subdivided into achromatic, epiplane objective, planachromatic, infinity corrected and semiplanachromatic. Thanks to their simple mechanical and optical nature, achromatic objectives classified as achromatic lenses, are usually the least costly and most commonly used objective lenses in microscopy. As a rule, these microscopes consist of three lenses and are ideally suited for many standard laboratory microscopic experiments. The optical defects of the achromatic microscope objectives are not resolved as in the case of, say, planachromatic microscope objectives, which usually remove the curvature of the light field that appears in a microscopic image and is finer in comparison.
Microscope lighting: As far as microscope illumination is concerned, we subdivide the microscopes in the shop into incident light, incident fluorescence light and transmitted light. In comparison to transmitted light microscopes, the object being presented is not trans-illuminated in incident light microscopes. In an incident light microscope, the specimen is lit from the direction of the objective, often from the specimen itself. Fluorescence microscopes use the physical effect of fluorescence for the microscopy of samples. Thus, fluorescence dyes are induced by the illumination of a certain wavelength and, a few nanoseconds later, light is released at a different wavelength. Special filters guarantee that only light produced is detected.
Microscopy contrast methods: As far as the contrast approach is concerned, we distinguish between incident light fluorescence, incident light bright field, dark field, transmitted light bright field and phase contrast. Some microscopic organisms, such as living cells or bacteria are almost non-transparent and can hardly be seen with a traditional light field microscope. There are also specific contrast methods of microscopy, such as the dark background image dark field) or the commonly utilized phase contrast process, for which special objective lenses and a condenser are needed.
Microscopes and microscopy - accessories
In our collection of microscopes, we only stock high-quality microscopes from recognized manufacturers. Robust microscopy systems are distinguished by their robust efficiency, high level of diagnostic efficacy and service life, as well as the versatility of the ability to swap microscope sections or attach accessories. Depending on the model and manufacturer you can purchase a range of replacement parts and accessories for your microscope online, such as different lenses, fittings, filters, eyepieces, condensers, stands, stages, sample clips, camera adapters, lighting elements as well as many other accessories and microscope components on sale.

Essentially, the configuration of the modern microscope usually consists of the following microscope components:
- Eyepiece - into which you look, enlarges the intermediate image created by the objective lens and projects it on the retina of the eye
- Tube - binocular, often oblique tube on the upper end of the microscope
- Objective - located on the microscope above the subject/subject being viewed
- Objective revolver - allows a rapid change of objective lens
- XY cross-table - movable mechanical stage for the exact alignment of the object to be displayed on the microscope stage
- Stage - working plate with a hole in the centre, including sample clips;
- Condenser - a microscope lens device below the object stage, an optical light collector that concentrates the light
- Condenser drive - buttons for concentrating on the illuminated and activated planning
- Lighting - microscope lamps or mirrors that are mostly used to illuminate preparations
- Field diaphragm - restricts the illuminated area to the item being observed
- Frame with coarse and fine focussing - usually two shifting wheels for positioning
- Microscope foot - baseplate of the microscope.
