LENS: Lenses

Classical lens optics is essential for the understanding and design of everything from Space Telescopes to photocopiers to iPhones. The experiment gives you some familiarity with concepts relevant to lenses in general, is a good introduction to chi-squared analysis, and is an introduction to chromatic and other lens aberrations.

Optics Video Tips

From Prof. Robin Marjoribanks

• Finding second surface of an optic.
• Finding focus from speckle.
• Aligning a lens to a laser beam.
• Aligning a Beam Expander.
