Variables

Spot Diameter

Spot Diameter refers to the width of the laser beam at its focal point or the point where it strikes a surface.

Symbol: d_spot

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Formulas to find Spot Diameter

Focal Length of Lens

Focal Length of Lens is determined when lens is focused at infinity. Lens focal length tells us angle of view and how much of scene will be captured. The longer focal length, a narrower angle of view.

Symbol: f_lens

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Formulas to find Focal Length of Lens

Beam Divergence

Beam Divergence is the angle made by the beam incident on surface of metal.

Symbol: α

Measurement: AngleUnit: rad

Note: Value should be greater than 0.
