Abstract:
A reflectance detection method in which a workpiece is irradiated with a laser beam and reflectance is detected, irradiating, with a light amount H0, the workpiece with a laser beam with a first wavelength X1 shorter than a detection-target wavelength X and detecting a light amount H1 of reflected return light, irradiating the workpiece with a laser beam with a second wavelength X2 longer than the detection-target wavelength X with the light amount H0 and detecting a light amount H2 of reflected return light, and employing H calculated based on an expression shown below as the light amount of return light obtained when the workpiece is irradiated with the detection-target wavelength X and calculating reflectance obtained when the workpiece is irradiated with the detection-target wavelength X based on H/H0. H=H 1+( H 2− H 1)×( X−X 1)/( X 2− X 1)

Claim (Index 5):
The reflectance detection apparatus according to  claim 4 , wherein\n the laser beam irradiation means further includes a collimator disposed on a downstream side of the coupler and the laser beam that results from the coalescence by the coupler is converted to collimated light by the collimator.
