acceptance_angle
- ofiber.basics.acceptance_angle(NA, n_outside=1)[source]
Find the acceptance angle for a cone of light in/out of an optical fiber.
This is the half-angle measured from the normal to the fiber face to the edge of the entering (or exiting) cone of light.
The face of the optical fiber is in a medium that defaults to air, but whose index can be specified.
- Parameters:
NA – numerical aperture of the fiber [–]
n_outside – (optional) refractive index of medium outside fiber [–]
- Returns:
maximum entrance/exit half-angle of the fiber [radians]
