Enter the required details such as focal length, lens thickness, and refractive index into the calculator to determine the net power of the lens.
Thick Lens Calculation Formula
The following formula is used to calculate the net power of a thick lens:
Net Power = (n - 1) / (Focal Length - (n - 1) * Lens Thickness / n)
Variables:
- Net Power is the optical power of the lens (Diopters)
- n is the refractive index of the lens material
- Focal Length is the distance over which initially collimated rays are brought to a focus (mm)
- Lens Thickness is the thickness of the lens (mm)
