Lens marker formula. Pradeep Kshetrapal Tutorials Point. This equation is also known as the Gaussian lens formula and was discovered by. The lensmakers equation relates the focal length of a simple lens with the spherical curvature of its two faces.

Using lens formula the equation for magnification can also be obtained as m h2h1 vu f-vf f fu This equation is valid for both convex and concave lenses and for real and virtual images.

Refraction in thin lenses. Our mission is to provide a free world-class education to anyone anywhere. The Lens Makers Formula Lens manufacturers use the lens makers formula to manufacture lenses of the desired focal length.

It is used by lens manufacturers to make the lenses of particular power from the glass of a given refractive index. The radii of curvature here are measured according to the Cartesian sign convention. For different optical instruments lenses having different focal lengths are used.

Lens makers formula is the relation between the focal length of a lens to the refractive index of its material and the radii of curvature of its two surfaces. Consider a thin convex lens of focal length f and refractive index µ. Where is the distance from the lens to the object and is the distance from the lens to the image.

This is so-called as the formula helps lens manufacturers in finding the radii of curvature of the required lens. The derivation of lens maker formula is provided here so that aspirants can understand the concept more effectively. Lens manufacturers commonly use the lens maker formula for manufacturing lenses of the desired focal length.
