An achromatic lens is one without chromatic distortion (gives no colour fringing). The achromatism has no direct relation to power.

Who invented the achromatic lens?

The achromatic lens was invented by English scientist John Dollond in the 18th century. He developed this lens design to address issues of chromatic aberration in optical instruments like telescopes and microscopes, resulting in improved image quality.


A sentence using the word achromatic?

What is an achromatic lens?

Point in a chromaticity diagram representing an achromatic color.Achromatic means without color so an achromatic point could be black or white.It is the point at which starch no longer gives a positive result (blue color) to Iodine test.


What does An achromatic lens consists of?

An achromatic lens consists of a compound lens made up of two or more elements with different types of glass to minimize chromatic aberration. This design allows the lens to focus multiple wavelengths of light to a single point, resulting in improved image quality.


What is the relation between power of lens and focal length?

n - 1D = --------rwhere:D = dioptric power of the surface,n = the index of the material that the surface is made from,r = the radius of curvature of the surface, in metersand where the surface is in air.


How lens power change with curvature of lens surface?

The lens power increases as the curvature of the lens surface becomes steeper. A lens with a larger radius of curvature will have a lower power, while a lens with a smaller radius of curvature will have a higher power. This relationship is described by the lensmaker's equation, which relates the power of a lens to the refractive index of the lens material and the radii of curvature of its surfaces.


How do you calculate microscope power?

the objective lens has the power of that lens inscribed on it


If a microscope had a power of magnification of 200x what would the power of the objective lens be if the eyepiece lens is 10x?

The total magnification of a microscope is calculated by multiplying the power of the objective lens by the power of the eyepiece lens. Given a total magnification of 200x and an eyepiece lens power of 10x, the power of the objective lens would be 200x/10x = 20x.
