The Focal Distance Calculator computes the focal distance based on the radius of curvature of a lens or mirror. By inputting the radius of curvature in millimeters (mm), users can easily calculate the focal distance using the formula:
Focal Distance Formula
\[ \text{FD} = \frac{R}{2} \]
- FD: Focal Distance (mm)
- R: Radius of Curvature (mm)
How to Calculate Focal Distance?
To determine the focal distance, simply divide the radius of curvature by 2.
Example Calculation
If the radius of curvature is 100 mm, the focal distance would be: \[ \text{FD} = \frac{100}{2} = 50 \text{ mm} \]
