Q
Spherical Abberation
A
Focal point changes due to spherical nature of lens
Solution=use different lenses to minimize lens effect
1
Q
3 Aberrations
A
Spherical
Chromatic
Curvature of Field
2
Q
Chromatic Abberation
A
Dispersion causes different focal points for each color
Solution=achromat lens, semi-apochromat,apochromat
3
Q
Curvature of Field
A
Different parts of spherical lens focus on different points-cannot fix using monochromatic light
Solution=use “plan” lens
4
Q
Isotropic
A
Isometric-cubic
5
Q
Anisotropic
A
Uniaxial - tetragonal, hexagonal
Biaxial- orthorhombic, monoclinic,triclinic
