TSI concave lens 50mm from the United States

United States*TSI concave lens50mm: 610092 is a -50mm or 100mm cylindrical lens (used for broadcasting light in one direction). The 610092 is a 50mm or 100mm cylindrical lens (used to spread light in one direction).
TSI concave lens, also known as negative spherical lens, has a thin lens and thick periphery, forming a concave shape, hence it is also called concave lens. Concave lenses have a diverging effect on light. After parallel rays are deflected by a concave spherical lens, they diverge and become divergent rays, which cannot form a real focal point. Along the reverse extension line of the scattered rays, they intersect at point F on the same side of the projected rays, forming a virtual focal point (concave lenses have two virtual focal points).
It is divided into three types: biconcave, plano concave, and convex concave lenses. The line connecting the centers of curvature on both sides is called the principal axis, and the point O of its * is called the optical center. The light passing through the optical center does not refract from any direction. A beam of light parallel to the main axis, refracted on a concave lens and diverging in all directions, will be refracted at a point F on the same side as the light source, which is called the virtual focal point. There is one on each side of the lens. Concave lens, also known as divergent lens. The focal length of a concave lens refers to the distance from the focal point to the center of the lens. The larger the radius of a lens, the longer its focal length. If it is a thin lens, the focal lengths on both sides are equal.
A transparent body with both sides being spherical or one side being spherical and the other side being flat, and the middle part being thinner, is called a concave lens. When used in optically sparse media, it can diverge the incident light beam, hence it is also known as a diverging lens. Also known as a negative lens due to its negative focal length. For thin concave lenses, the imaging formula, lateral magnification formula, and symbol rule are the same as those for convex lenses.
The image formed by TSI concave lens is always smaller than the upright virtual image of the object, and concave lens is mainly used to correct myopia. Myopia is mainly caused by the deformation of the crystalline lens, which leads to premature convergence of light in front of the retina. Concave lenses play a role in diverging light rays, forming an upright, reduced virtual image that increases the distance between the images and falls precisely on the retina.
The geometric drawing of TSI concave lens imaging follows the same principle as convex lens imaging. From the top of the object, there are also two straight lines: one parallel to the main optical axis, which is refracted into divergent rays after passing through a concave lens, and returns this refracted ray in the opposite direction to the main focal point; The other line passes through the optical center point of the lens, and these two lines intersect at one point, which is the image of the object.

TSI concave lens, also known as negative spherical lens, has a thin center and thick edges in a concave shape, hence it is also called concave lens. Concave lenses have a diverging effect on light. Myopia glasses are concave lenses.
TSI concave lenses are divided into double concave, flat concave, convex concave (note: convex concave lenses have a greater concavity than convexity, and concave convex lenses have a greater convexity than concavity!) and other forms.
