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?
John Dollond invented the achromatic lens. He used a combination of crown and flint glasses to construct the lens.
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.
If the eyepiece lens of a microscope has a power of 10x and the objective lens has a power of 43x then what is 430x?
The Power
Which lens is the medium lens on the nosepiece?
low power
Which lens provides more magnification-a low power or a high power?
A lens of short focal length has a greater power (than a lens of large focal length)
What does achromatic mean?
Achromatic means "without color". An achromatic lens is a lens that is virtually free from prismatic color distortions.
Who invented the achromatic lens?
John Dollond invented the achromatic lens. He used a combination of crown and flint glasses to construct the lens.
How is aberration corrected?
using an achromatic lens
Do achromatic lens refract of reflect?
Refract
What are lens constructed so at avoid undesirable color effects?
Achromatic lens.
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.
A sentence using the word achromatic?
The distracting violet fringing of the image in the telescope was limited by the use of an achromatic lens system.
Achromatic lens Invented by whom and when?
John Dolland 1758
What does An achromatic lens consists of?
Achromatic Lenses consist of two or more elements, usually of crown and flint glass that have been corrected for chromatic aberration with respect to two selected wavelengths. by jay-j
Why a small focal length convex lens is used in simple microscope?
because manifying power has inerse relation with that of focal length
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
