Abstract
(EN)
This light irradiation device is provided with a first optical fiber which is arranged on the tip side of the light irradiation device, and a second optical fiber which, arranged on the base side of the first optical fiber, is connected at the base end to a light source and is connected at the tip end either directly or indirectly to the first optical fiber. The first optical fiber has a first core, the second optical fiber has a second core, and the minimum value of the numerical aperture of the first optical fiber is greater than the minimum value of the numerical aperture of the second optical fiber.
