Beam Spread Calculator

Example Calculations

Example 1:

• Distance to Surface (D): 10 in
• Angle of the Beam (A): 0.5 radians

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:

• Distance to Surface (D): 20 in
• Angle of the Beam (A): 1 radian

Calculation:

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