Abstract
PURPOSE:To simply perform the check by many kinds of light sources, by using rotatable polyprisms providing different light sources every plane. CONSTITUTION:The triangular prisms 3 fixed with an incandescent lamp, a fluoresscent lamp and an electric bulb are located up and down in the external box 1 so that the light sources of the upper and lower sides are of the same type, and they can be rotated cooperatively via the belt 4, and the backgrounds 2, 2' taking the front sids as white color are located with hinge at the back, and the back side of the background 2 and the rear side of the external box 1 facing to the background 2 are takne black in color. Further, after suitably selecting the backgrounds 2, 2' according to the color of inspected solution, the inspected solution is located between the upper and lower prisms 3, the light sources are flickered with the rotary drum type switch while cooperatively rotating the prisms 3 to inspect the foreign material in the inspected solution. Thus, the inspection by three kinds of light sources can continuously be made easily.
