A wide field of view telescope having two concave and two convex reflective surfaces, each with an aspheric surface contour, has a flat focal plane array. The method includes forming a plurality of pleats in a filter media that extend along a front face and a rear face. A cooling unit moves air through the gap and across the surface of hardware cards connected to the hardware plane in order to cool the hardware plane and the hardware cards. The layer sets to create the liquid barrier and for fixing the board to the sheathing with spaces left between the barrier and the valleys for water runoff across the sheathing. Compositions and methods for their preparation and use as diagnostic imaging and therapeutic agents are also disclosed. Rotation of the eccentric shaft moves the clamp arm toward the contact portion of the ring so that the mandrel can be clamped between the clamp arm and the contact portion.
