Question:

What is the lens makers formula?

Updated On: Apr 29, 2024
  • 1f=(μ+1)(1R1−1R2)\frac 1f=(μ+1)(\frac {1}{R_1}-\frac {1}{R_2})
  • 1f=(μ−1)(1R1−1R2)\frac 1f=(μ-1)(\frac {1}{R_1}-\frac {1}{R_2})
  • 1f=(μ+1)(1R1+1R2)\frac 1f=(μ+1)(\frac {1}{R_1}+\frac {1}{R_2})
  • 1f=(μ−1)(1R1+1R2)\frac 1f=(μ-1)(\frac {1}{R_1}+\frac {1}{R_2})
