Microscopes
Microscopes are composed of a magnifying lens and an eyepiece that join together in a tube, an illuminated stage where the object being observed is placed and a tripod to secure the optical components. The source of light for our microscopes is generally a small bulb attached to the tripod of lenses that can be adjusted (via a lens or system of lenses near the bulb) and fixed behind the illuminated area. The condenser for our microscopes is a complicated system of lenses or mirrors that reproduce the light on the surface of the object. The lens for our microscopes amplifies the object so that this magnified image can be viewed in the eyepiece. Microscopes also have two eyepieces to allow the object to be viewed with both eyes. This distinguishes a microscope using transmitted light that passes through very thin transparent objects, and microscopes using reflected light for analyzing surfaces of opaque objects. We offer a range of microscopes for various purposes, such as for use in laboratories, research, in the office or for a hobby. There are even microscopes for the application in schools. Since young students do also face microscopy in class, microscopes with high accuracy are necessary to guarantee an optimal education fun.  All of these microscopes can be connected via a USB port to a computer making it possible to document images or record videos for analysis or even to a projector to display the images to a wider audience. We also offer a micro-ocular, which can affordably convert a standard microscope into a videoscope allowing for images to be transferred directly to a computer. In addition to that, extensive accessory is available for our microscopes.

Using a microscope When using a microscope, a few small errors might occur: - If the magnification has been set too high. For observing sections of simple objects, a magnification of between 50x and 300x is sufficient. Only when very thin objects with a microtome or samples are being observed is it suitable to increase the magnification. Likewise, we use magnifications of 1000x or higher for the analysis of blood. - The preparation deteriorates with a false adjustment of the lens. With higher magnifications, it is possible to first adjust the focus before the lens affects the sample. As such, for a suitable adjustment, the lens will be closed against the stage. After, the clarity of the eyepiece can be adjusted with care.
Cleaning Microscopes. A prerequisite for obtaining clear images with the microscope is that the lens is clean. The biggest problem is dust. It can come from the objects being observed or dust in the environment that the miscroscope is being used. It is very important to protect the lenses from dust to ensure that it does not have the opportunity to damage the lens surface. When the device is not in use, ensure that it is covered to protect it from exposure to dust and make sure that the cover is kept clean to make sure that it is protecting the microscope. It's important to differentiate between the kinds of dirt on the lenses when they are going to be cleaned: dust particles (residue from glass slides or fabrics, etc.) and dirt in general (fingerprints, etc).

Microscopes are formed by different parts: an optical and a mechanical part. Here follows a short description of these parts:  - Ocular: Are the lenses situated the closest to the beholder viewer  - Arm: Situated perpendicullary to the base, they can be vertical or arched, so that they can joined to the base.  - Stage: Is the part that holds the sample, it consists on two grippers and the hole from which comes the light to    observe the sample  - Macrometric fitting: An screw for focus and choose lenses on a quick way  - Micrometric fitting. An screw for focus and choose lenses on a slow way  - Stage fitting: An screw that fits the stage  - Base: is the part that holds the microscope  - Light souce: It is used to light the samples or items to be observed, it is isolated on the base.  - Grippers: Two grippers located on the stage. Their aim is to hold the samples  - Objective lens: The lense situated the closest to the sample  - Revolver: Is the part that holds the set of objective lenses, it allows to change them.  - Tube: Is the part were the ocular is, it holds the revolver with the objective lenses on the bottom and the oculars on    the top. Information concerning the use of microscopes:  - Microscopes should be installed straight and safely  - Mircorscopes need to be connected to a socket  - Specimen stage on lowest level  - Object needs to be in the middle of the specimen stage  - control illumination level with the help of the aperture Different types of microscopes Simple Microscopes: They just use a single magnifying glass Composite Microscopes: They are formed by a kit of glasses, in a way that they allow to magnify the image through them. (optics microscopes). Electronic Microscopes: They use electrons instead of visible light (fotons) to provide images of small items. Those icroscopes increase the speed of electrons to get a shorted wavelength and a better resolution (electrons have a wavelength rather small than visible light, so they are able to break up very small structures) It gives a magnification capacity about 500.000 magnifications compared to other optical microscopes. The images obtained are on black and white as they use electrons instead of light. The electronic spot is produced by a Wolframic cathode.  Microscopes of reflected light: These microscopes are used mainly to observe transparent and liquid preparations. They are specially used in blood analyse, cells, tests in plants. Classical reflected light microscopes have a really short working distance, under 4 mm. This is why these microscopes are suitable for very thin solutions. On the image above you can observe a cell that has been tinted for better observation trough microscope  Solutions are situated on the samples holder and covered with the samples cover lid. Reflected light microscopes are usually offered with a full range of magnification glasses (from 40 to more than 1000). For works of 1000 magnifications it is necessary to put a drop of oil immersion to seal the space between the sample holder and the cover lid. Images until 400 magnifications can be seen without any special technic. The magnification on reflected light microscopes can be increased by changing the oculars Stereo Microscopes using reflected or transmitted light: These microscopes are typically used to view large objects. Their range of uses includes analysing insects, plants, coins or for testing materials. The majority of reflected light microscopes have a working distance of 40mm, making these microscopes ideal for working with large objects or for testing different materials. Normally we offer these microscopes as models with two eye pieces. Fluorescence Microscopes: Used to reveal natural fluorescent molecules, or to reveal an added fluorescence, when detecting antibodies. On this image you can see a sample that has not been treated, because it is fluorescent by itself. This circumstance makes tinting unnecessary In immunity fluorescence a fluorescent dye (almost always FITC) is added to an antibody. These antibodies can be produced on a very specific way to concrete biological structures. The dyes are extremely selective, but not so intensive as in traditional secondary fluorescence.                    For applications that require to keep images there are trinocular microscopes. They consist on binocular microscopes with an additional tube that allows to install an USB camera that recordes images. These images can later be transferred to a PC or a laptop. It also offers the possibility to connect a microocular to the binocular microscopes. This microocular is simply set to the ocular of the microscope. This gives the opportunity to turn microscopes on video microscopes in an economical way.                     Requirements to the microscopes: Since microscopes are used in different areas, their equipment differs. There are normal microscopes with a magnification from 400 to 600-fold. There are also special lighting systems available which makes the examination of low-contrast objects possible.
