Calculate Hyperfocal Distance





Formula

To calculate the Hyperfocal Distance (HD):

\[ HD = \frac{FL^2}{CoC \cdot F-s} \]

What is Hyperfocal Distance?

Hyperfocal distance is the closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp. It is the lowest possible frequency required for a system, usually a tube with sound moving through it, to be resonating.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ HD = \frac{50^2}{0.02 \cdot 8} = 15625 \]

The hyperfocal distance is 15625 mm.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ HD = \frac{35^2}{0.03 \cdot 11} = 3712.12 \]

The hyperfocal distance is 3712.12 mm.
