Acompound light microscopeis a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. Although sometimes found as monocular with one ocular l...
Purkinje obtained an achromatic compound microscope in 1832, and began examining nervous tissue and other biological samples. 在1832年,浦肯野获得了一台消色差显微镜,于是他开始研究神经组织和其他的生物标本。 The compound microscope consists of two convex lenses with short focal length, the objective and...
The body of the compound light microscope is the main part of the microscope, not to include the lights, focusing block, or stand of the microscope. The objective lenses and eyepiece are a part of the body of the compound light microscope. Arm The arm of the compound light microscope can...
Microscopy Compound Microscope – Resolution The ability of a lens to distinguish between two points as separate objects Depends on wavelength of light – usually maximum resolution is wavelength / 2 Maximum for light microscope is about 0.2 microns or about 2000x Microscopy Types of Modern Microscopy...

Principles of light microscopy: With a compound light microscope, we can examine very small specimens as well as some of their fine detail. A series of finely round lenses form a clearly focused image that is many times larger than the specimen itself. The magnification is achieved when light...
Lenses in a Compound Microscope The objective lens system use a small focal distance, the distance between the lens and the specimen or object being examined. The real image of the specimen is projected through the objective lens to create an intermediate image from the light incident on the le...
For this microscope, all the glass optics are coated to reduce unwanted reflections. Essentially, lenses/optics serve to gather and transmit light back to the eyes thus making the image visible. As light moves through (transmitted) the lenses, some are reflected off the surface and lost. This...
In this microscope, light is used to illuminate the objects. The glass crystal lenses in it magnify the image of the object and make it fall on the retina of the observer's eye. There are two lenses at the ends of the tube. The lens closest to the eye is called the eyepiece lens....
While the eyepieces and the objective lenses create high magnification, a condenser beneath the stage focuses the light directly into the sample. What is a Compound Microscope Used For? Most people think of a biological microscope when they hear the term compound microscope. This is true that a...
