fénymikroszkópok

Fénymikroszkópok, also known as optical microscopes, are scientific instruments used to magnify small objects that are not visible to the naked eye. They work by passing visible light through a specimen and then through a series of lenses. The lenses refract the light in such a way that the image of the specimen is magnified and projected to the observer's eye or a camera.

The basic components of a fénymikroszkóp include a light source (often a lamp), a condenser to focus the light onto the specimen, a stage to hold the specimen, objective lenses to provide initial magnification, and an eyepiece lens (or ocular lens) to provide further magnification. Different objective lenses with varying magnifications are typically mounted on a revolving nosepiece, allowing the user to switch between them easily.

Fénymikroszkópok are widely used in various fields such as biology, medicine, materials science, and education. They are essential tools for observing cells, tissues, microorganisms, and the fine details of materials. Common types of fénymikroszkópok include bright-field microscopes, dark-field microscopes, phase-contrast microscopes, and fluorescence microscopes, each offering different ways to visualize specimens based on their optical properties. The resolution of a fénymikroszkóp is limited by the wavelength of light used, typically around 200 nanometers.
