Optics : Aberration

Question 1

What is a property that causes light to be spread out over an area rather than focused on a particular point?

Answer 1

Abberations

Question 2

Can abberation images be blurred, distorted or both?

Answer 2

Both

Question 3

What are the two types of abberations?

Answer 3

Monochromatic

Chromatic

Question 4

What type of aberration present with with a single wavelength of light?

Answer 4

Monochromatic

Question 5

What are examples of abberations?

Answer 5

Spherical aberration 
Coma 
Oblique Astigmatism 
Field curvature 
Distortion

Question 6

What is spherical aberration most significant for?

Answer 6

Contact lenses

Question 7

What do you measure aberration with?

Answer 7

Aberrometers

Question 8

What type of aberration present wavelengths of color?

Answer 8

Chromatic

Question 9

What are the types of chromatic aberration?

Answer 9

Transverse

Longitudinal

Question 10

What type of chromatic aberration :
Red, yellow, blue light focus at separate points in the VERTICAL plane
Image size varies with wavelength
Most of an issue with glasses

Answer 10

Transverse Chromatic Aberration

Question 11

What type of Chromatic Aberration :

Different wavelengths focus at different points on the HORIZONTAL axis due to the dispersion properties of lens material

Answer 11

Longitudinal Chromatic Aberration

Question 12

What colour of light focus at separate points in the vertical plane?

Answer 12

Red, Yellow, Blue

Question 13

Why do different wavelength focus at different points on the horizontal axis?

Answer 13

Dispersion properties of lens material
