Wide angle, limited rotation, micro-lens scanning of DNA arrays, microscope slides, biological materials, etc., translated beneath the arc path of a micro-lens (18). Micro-lens (18), on low moment of inertia oscillating arm (19), while light source (24), detector (10, 95), and supplementary lenses (18b, 27) are stationary, achieve rapid, wide angle pixel-based microscopy. Aspheric micro-lenses achieve high N.A.. The preferred stationary light path extends to the axis of rotation (A) in plane parallel to the scan plane, at a substantial angle to the neutral position of arm (19). With arm position detected, the pixel data acquired from limited arc scans is converted by interpolation and timing to raster format. Dithered deflection of the light path upon the micro-lens (18) can straighten the scans. Auto focus raising and lowering stage (50) by actuator (44), while object (2) translates, enables rapid, wide range confocal microscopy. Transmission, reflection and fluorescence detection microscopes are shown.
