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 are lens constructed so at avoid undesirable color effects?
Lenses are constructed with specialized coatings or materials to reduce chromatic aberration and color fringing, which can cause undesirable color effects like color fringing and color distortion. These coatings help to improve lens performance and produce images with accurate color representation.
What is the pole of a lens?
The pole of a lens is the midpoint of the lens' geometric axis. It is where the principal axis intersects the lens.
What is Another name of convex and concave lens?
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
What does a 58mm lens mean?
A 58mm lens refers to the diameter of the lens barrel at the front of the lens. This measurement is important for selecting compatible lens filters and accessories. It does not directly relate to the focal length or zoom capability of the lens.
What does achromatic mean?
Achromatic means "without color". An achromatic lens is a lens that is virtually free from prismatic color distortions.
How is aberration corrected?
using an achromatic lens
Do achromatic lens refract of reflect?
Refract
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?
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 is achromatic lens and what is its relation to power and dispersive power?
An achromatic lens is a type of lens designed to minimize chromatic aberration, which causes colors to focus at different points. It is made by combining two different types of glass with varying refractive indexes to reduce this effect. The power of an achromatic lens is related to its ability to focus light without chromatic aberration, while its dispersive power is diminished due to the combination of different glass types.
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.
Does achromatic mean colorless in Greek?
Yes. Achromatic does mean colorless in Greek.
When something lacks hue it is referred to as?
When something lacks hue, it is referred to as achromatic or neutral.
What is the word for having no definite color?
Achromatic means being without color or having no color.
Who invented the two lens system?
The use of a two lens telescope is credited to three people of Netherlands , Hans Lippershey and Zacharias Janssen, and Jacob Metius . Galileo improved on their designs and is generally given the credit of inventing the telescope.Robert Hooke was the first to use a two lens microscope.
