Online Calculators since 2009
The Optical Power Calculator will calculate the:
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/
|Optical power of a system composed by two lenses in contact calculation|
|Pcontact = 1/F1 + 1/F2|
Pcontact = 1/ + 1/
|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 = ×
|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.
We hope you found the Optical Power Calculator useful with your Physics revision, if you did, we kindly request that you rate this Physics calculator and, if you have time, share to your favourite social network. This allows us to allocate future resource and keep these Physics calculators and educational material free for all to use across the globe. We believe everyone should have free access to Physics educational material, by sharing you help us reach all Physics students and those interested in Physics across the globe.
The following Physics tutorials are provided within the Optics section of our Free Physics Tutorials. Each Optics tutorial includes detailed Optics formula and example of how to calculate and resolve specific Optics questions and problems. At the end of each Optics tutorial you will find Optics revision questions with a hidden answer that reveals when clicked. This allows you to learn about Optics and test your knowledge of Physics by answering the test questions on Optics.
