If we design an achromatic lens, as shown in Figure 4.2, with two different types
of glass, the two selected wavelengths (frequently C and F) will have the same
focal length, but it will be different for all other colors. The focal length as a
function ...

From this equation, the following conclusions may be drawn (i) CO, andu>2 are
positive quantities, therefore/, and/2 must be of opposite sign. Hence in
achromatic lens combination if one lens is convex, the other must be concave. (ii)
The two ...

Optical Principles and Technology for Engineers
An ultraviolet achromatic lens can be designed using two fused silica elements. A
plano-convex fused silica lens with a 10.54 mm radius of curvature of the convex
surface and a thickness of 3.25 mm has a focal length of 20.77 mm at 250 nm.

Having thus shown the origin of the negative achromatic lens, I may be allowed
to state the motives and reasonings which guided me in the computation of the
curves, and what appears to me to constitute the advantages it is found to
possess.

An achromatic lens system (achromat is a compound lens of one lens each of flint
- and crown glass, figure 102) is nearly free of chromatic aberration. It can be
completely free of it only for two spectral colours, e.g. for red and blue. For the
other ...

An achromatic lens doublet is formed by placing in contact a convex lens of focal
length 20 cm and a concave lens of focal length 30 cm. The dispersive power of
the material of the convex lens is 0.18. Determine — (a) The dispersive power of
...

An achromatic lens is strictly true only for the two wavelengths e.g., red and violet.
Other colours may be present in very small amounts. So the system is not
achromatic for all colours at a time. • In achromatic combination the lenses are ...
