SUMMARY

Dispersion of light can indeed occur through lenses, specifically convex and concave types, as they can scatter white light into its constituent colors. This phenomenon is closely related to chromatic aberration, which is the failure of a lens to focus all colors to the same convergence point. The discussion highlights a personal experience with high-index refraction glass lenses that exhibited significant dispersion, allowing the user to observe distinct spectral lines from sodium and mercury vapor lamps.

PREREQUISITES
  • Understanding of chromatic aberration in optics
  • Familiarity with lens types: convex and concave
  • Knowledge of light dispersion and its principles
  • Basic concepts of refraction and index of refraction
NEXT STEPS
  • Research the effects of chromatic aberration on image quality in optical systems
  • Explore high-index refraction materials and their applications in eyewear
  • Study the principles of light dispersion and its measurement techniques
  • Learn about optical design software for simulating lens performance
USEFUL FOR

Optics enthusiasts, optical engineers, and anyone interested in the properties of lenses and light behavior in various materials.

Can dispersion of light take place through lens, i.e. can lens (incl. Convex and Concave) scatter white light into its constituents?

Do a little reading on "chromatic aberration."
 
I once had eyeglasses that used a then-new type of glass with a higher index of refraction which allowed the lenses to be thinner. (I'm very nearsighted and have to use a strong lens prescription.) That glass also had a rather high dispersion, so when I looked at a street-lamp through the outer part of the lens, near the edge, I saw a nice little spectrum. I could even make out spectrum lines in sodium and mercury vapor lamps!
