Abstract
A first lens configured to convert light from the objective lens into parallel light includes a concave lens part having a concave curved face in a center portion of a flat face, and a convex lens part having a convex curved face around a flat face. Further, the first lens includes first and second regions configured to diverge light through the flat face and the concave curved face and a third region configured to collect light through the convex curved face and the concave curved face. When the sample is on a sample table and sealed in a two-dimensional electrophoresis substrate, light totally reflected by a side surface of the objective lens enters the second region. In contrast, when the sample is directly on the sample table, the light enters the third region.
