摘要： In order to determine white blurring objectively and without irregularity, this surface inspection device is provided with an opening, multiple measurement units, an acquisition unit, and a calculation unit. The opening defines an aperture plane used for measurement purposes. The multiple measurement units each has a light emitting unit and a light receiving unit, and, seen in a perspective planar view from the imaginary normal line of the aperture plane, are arranged in mutually different directions with respect to the opening. For each measurement unit, the acquisition unit acquires a detection value relating to brightness, corresponding to the light received through the aperture plane by the light receiving unit after being emitted from a sample surface in response to being irradiated by light from the light emitting unit through the aperture plane. The calculation unit calculates an evaluation value relating to the degree of variation of the multiple detection values obtained by the acquisition unit for each of the measurement units. Further, a first angle formed between the first optical path of light travelling from the light emitting unit towards the aperture plane and the normal line of said aperture plane, a second angle formed between said normal line and a second optical path of light travelling from the aperture plane towards the light receiving unit, and a third angle formed between the first optical path and the second optical path are the same in each of the multiple measurement units.

摘要： A spectroscopic unit and spectroscopic device according to the present invention are provided with a filter that is provided with a plurality of optical filter elements disposed in order from the entrance side to the exit side of light under measurement and has different transmission wavelengths corresponding to entrance positions along a first direction. A first optical filter element from among the plurality of optical filter elements is tilted with respect to a second optical filter element disposed adjacently to the first optical filter element as a result of the first optical filter element being rotated by a prescribed angle with a third direction that is perpendicular to both the first direction and s second direction from the entrance side to the exit side as the axis of rotation thereof or being rotated by a prescribed angle with the first direction as the axis of rotation thereof.
摘要翻译：根据本发明的分光单元和分光装置设置有滤波器，该滤波器设置有从被测光的入射侧到出射侧依次设置的多个滤光器元件，并且具有与入射位置相对应的不同透射波长沿着第一方向。由于第一光学滤波器元件以第三方向旋转预定角度，所以多个光学滤波器元件中的第一光学滤波器元件相对于设置为与第一光学滤波器元件相邻设置的第二光学滤波器元件倾斜，其从入口侧到出口侧的第一方向和第二方向均垂直于其旋转轴线或者以第一方向作为其旋转轴线旋转预定角度。
