SUMMARY

Using lenses to magnify a viewing area is feasible, but specific constraints must be considered. The discussion highlights that achieving a 10:1 magnification of a 10-inch diameter area down to 1 inch is impractical due to the limited object-image distance of only 2 inches. Real-world optics, including geometrical and fresnel optics, impose significant limitations on such configurations. Therefore, while single or multiple lenses can magnify images, the desired specifications in this case are not achievable.

PREREQUISITES
  • Understanding of geometrical optics principles
  • Familiarity with lens types and their properties
  • Knowledge of magnification calculations
  • Basic comprehension of optical distances and angles
NEXT STEPS
  • Research the principles of geometrical optics in depth
  • Explore different types of lenses and their applications
  • Learn about magnification formulas and calculations
  • Investigate the limitations of fresnel optics in practical applications
USEFUL FOR

Optics enthusiasts, physics students, and professionals in optical design looking to understand the limitations and applications of lenses for magnification purposes.

Hello,

Is it possible by using one or combination of more lenses to magnify the viewing area.

What do you mean by a "large viewing area"? Given even a single lens you can achieve a magnified image, and odds are given a few constraints like yours you can use geometrical optics to find a pair of lenses that might work.

Edit: After taking a closer look at your diagram it's looking like you want to image a 10" dia. area down to 1" (10:1 magnification), but the overall object-image distance is only 2". This sounds like it's just not possible using real-world optics (even fresnel optics) given the incident angles involved.
