Abstract: A multiple element color-corrected doubly telecentric lens and imaging system useful for imaging multiwell plates is described. The lens contains a biconvex field lens element L1, a positive meniscus lens element L2, concave toward the incident light side, a double-Gauss lens element group, a positive meniscus lens element L10, convex toward the incident light, a positive meniscus lens element L11, convex toward the incident light, and a plano concave field flattener lens element L12, concave toward the incident light side. The lens is very sensitive, and can be used to image scintillation proximity assays in multiwell plates.
