PURPOSE: Spectral-characteristics measuring device and method of a photovoltaic detector, and internal-quantum-efficiency measuring device and method of a photovoltaic detector are provided to decrease error due to the spatial un-uniformity of the radiance of spectral light and to increase the radiance of the spectral light by measuring differential spectral responsivity through a integrating sphere. CONSTITUTION: A spectral-characteristics measuring device of a photovoltaic detector comprises a cavity(100), a first opening(102), a second opening(104), a sun simulating unit(110) and a light source(132a). The cavity spreads and reflects. The first and second openings are arranged on a straight line passing a central axis from the cavity and are formed on the cavity. The solar simulating unit supplies sun simulating light with wide line-width to a sample arranged on the exit of the second opening through the first opening. The light source supplies spectral light with narrow line-width to straight lines connecting/crossing the first opening and the second opening.

PURPOSE: A mechanical mount for cylindrical optical components with an automatic center alignment is provided to fix a target having different diameters by controlling the size of an internal space which is formed by a fixed groove. CONSTITUTION: In a mechanical mount for cylindrical optical components with an automatic center alignment, a housing(1) has a can shape. Two fixing jigs(2) having fixed groove is installed inside the housing. The fixing jigs are getting narrower from center to the outside. An actuating unit(3) is installed at least one side of the fixing jig and moves the fixing jigs to be speared from each other. The actuating unit is comprised of a rack(31) having a gear teeth and a pinion moving the rack.
