Alpine optics on how does this work
Nowadays it is hard to imagine our ordinary life without any kind of lenses, optical mirrors, and other optical appliances. So at alpine optics, we want to share how optics work in our modern world. The physics of lenses and spherical mirrors is to change the direction of light rays, creating images that are larger or smaller than the displayed object. Lenses are pieces of transparent material bounded by spherical surfaces. Like spherical mirrors, they create enlarged or reduced images of objects.Beam patterns help you visualize the paths of multiple beams, especially those striking a mirror or lens parallel to their main optical axis. The difference between lenses and mirrors is that a lens forms an image of an object behind it, while a mirror changes the appearance of an object in front of it.
Optical mirrors: concave and convex
Concave optical mirrors produce a converging beam of rays. All rays incident on such a mirror parallel to its main axis, after reflection, converge at a point called the focus. The distance between the focus and the mirror is the focal length of the mirror. The shorter the focal length, the stronger the magnification.A convex mirror produces a diverging beam of rays. When parallel beams strike a convex mirror, the reflected beams diverge. The focus of the convex mirror is located behind it, at the point from which these rays appear to radiate.
CAF2 cylindrical lens
Cylindrical, also plano-convex lenses are a type of lenses, the peculiarity of which is the presence of an axis in the direction of which the optical effect does not appear.Spherical lenses are widely used for the correction of astigmatic aberrations, in laser levels and for longitudinal image magnification.
Caf2 cylindrical lens are also widely used as spectacle lenses to correct astigmatism, in laboratory studies: particle velocimetry, laser-induced fluorescence. Besides, cylindrical lenses are used in such systems where it is necessary to obtain an image in the form of thin extended lines: laser levels, scanners.
