Abstract:
PURPOSE: To accurately radiate a laser beam to a position on the circumference around the visual line in a cornea.
CONSTITUTION: A laser beam from a laser light source 7 is transmitted from a laser beam outgoing end 5 via an optical fiber 6, and it is converged on the cornea Ec of a tested eye E via a condensing lens 4, two wedge prisms 3, 2, and a dichroic mirror 1.
