Beam Spread Calculator





Formula

The formula to calculate the beam spread is:

\(BS = 2 \times D \times \tan(A \times 0.5)\)

Where:

Example Calculations

Example 1:

Calculation:

\(BS = 2 \times 10 \times \tan(0.5 \times 0.5) = 2 \times 10 \times \tan(0.25) \approx 2 \times 10 \times 0.255 = 5.1 \text{ in}\)

Example 2:

Calculation:

\(BS = 2 \times 20 \times \tan(1 \times 0.5) = 2 \times 20 \times \tan(0.5) \approx 2 \times 20 \times 0.546 = 21.84 \text{ in}\)
