The number of lenses in the structure is more than that of achromatic lenses, less than the chromatic aberrations. The image quality is far better than the achromatic objective, which is close to the apochromatic objective. Can correct the color difference of red and blue color and the ...
Compound lensesIt's possible to make lenses that behave in more complex ways by combining convex and concave lenses. A lens that uses two or more simpler lenses in this way is called a compound lens.Sponsored links How do you measure the power of a lens?
An objective lens system for use within a microscope includes a convex and a concave spherical mirrors which are substantially concentric and which are arranged to be opposite to each other. In the objective lens system, an optical element is further arranged to be closer to an object side or...
Sandmarc also offers a wide variety of lenses, from wide angle macro through to 6x telephoto and even a microscope lens. All Sandmarc lenses come with a clip to attach them to your phone, but we found this slipped about easily, moving the lens from the ideal spot, plus it always takes ...

Compound Microscopes The compound microscope consists essentially of two or more double convex lenses fixed in the two extremities of a hollow cylinder. The lower lens (nearest to the object) is called the objective; the upper lens (nearest to the eye of the observer), the eyepiece. The cylin...
7.The Fluorescence Microscope The fluorescence microscope is a specially modified compound microscope furnished with an ultraviolet (UV) radiation source and a filter that protects the viewer’s eye from injury by these dangerous rays. The name of this type of microscopy originates from the use of...
sights- an optical instrument for aiding the eye in aiming, as on a firearm or surveying instrument eyeglasses,glasses,specs,spectacles- optical instrument consisting of a frame that holds a pair of lenses for correcting defective vision
The first microscope, the JOICO, was a brass compound monocular microscope with three objective lenses and considered a technological marvel in that era. The company remains at the technological forefront with a complete line of biological, digital and stereo models, with emphasis on adapting digital...
The Microscope Optical TrainModern compound microscopes are designed to provide a magnified two-dimensional image that can be focused axially in successive focal planes, thus enabling a thorough examination of specimen fine structural detail in both two and three dimensions. ...
