Abstract: An optical measurement device includes: a measurement region in which a measurement object is disposed; a light beam scanning unit that irradiates the measurement region with light beam and scans the light beam in a scanning direction intersecting with an irradiation direction of the light beam; a light receiving unit that receives the light beam that has passed through the measurement region and outputs a light receiving signal; a signal processing unit that outputs data indicative of a dimension in the scanning direction of the measurement object based on the light receiving signal; and an optical path cover that is configured to be removably attachable to a housing of the light beam scanning unit and covers an optical path of the light beam in a range from the housing to the measurement object.
