A darkfield type illumination apparatus for performing slide agglutination tests or the like. The apparatus comprises an elongated casing having an opening therein over which a transparent slide carrying the material to be illuminated is positioned. In the preferred form of the apparatus, a nonreflective surface is provided in the casing below the opening. An elongated light source is positioned below such surface. A pair of angularly bent elongated light conducting members are positioned on opposite sides of the casing with one end of the members located adjacent to the light source and the other end extending upwardly at an angle toward the opening so that rays of light transmitted through the members intersect near the opening to obliquely illuminate the material on the slide. Other configurations of the apparatus are also disclosed.
