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.

Abstract: The invention provides exemplary systems, devices and methods for manipulating and handling multi-well plates. In one exemplary embodiment, a system is provided which comprises a robot having a base member and at least one arm. The arm includes a grasping mechanism which is adapted to grasp the plate. Further, the grasping mechanism is configured to receive the plate in a repeatable and known location such that the location of each well relative to the grasping mechanism is known by the robot.
