Optical Power Calculator
The Optical Power Calculator will calculate the:
- Optical power produced by a single lens
- Optical power produced by two lenses in contact with each other
- Optical power produced by two lenses at a certain distance from each other
Note: Take the focal length of converging lenses as positive and that of diverging lenses as negative.
The optical power produced by a single lens is D (dioptre) |
The optical power produced by two lenses in contact is D (dioptre) |
The optical power produced by two lenses at a certain distance from each other is D (dioptre) |
Optical power of the single lens calculation |

P1 = 1/F1 P1 = 1/ P1 = |
Optical power of a system composed by two lenses in contact calculation |
Pcontact = 1/F1 + 1/F2 Pcontact = 1/ + 1/ Pcontact = Pcontact = |
Optical power of a system composed by two lenses in distance from each other calculation |
Pdistance = 1/F1 + 1/F2 - d × 1/F1 × 1/F2 Pdistance = 1/ + 1/ - × 1/ × 1/ Pdistance = - × Pdistance = - × Pdistance = × Pdistance = |
Optical Power Calculator Input Values |
Focal length of the first lens (F1) m |
Focal length of the second lens (F2) m |
Distance between the two lenses (d) m |
Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each optical power calculation, the Optical Power Calculator will automatically calculate the results and update the Physics formula elements with each element of the optical power calculation. You can then email or print this optical power calculation as required for later use.
