Charge neutralizer | Laser Focus World

Charge neutralizer

The photoionizer neutralizes electrostatic chargers on semiconductors, integrated circuits, and liquid-crystal displays. The Model L6107 photoionizer incorporates a soft x-ray tube that floods an object with photon-generating ions. By irradiating the air around an object, enough photons are produced to neutralize the electrostatic charges on the object. The x-ray tube operates at 9.5 kV and 200 µA and has a 120° coverage angle.

Tracks of heavy ions 'imprinted' in lithium fluoride crystals. At the top, spot tracks observed under a fluorescence microscope in plates perpendicular to the heavy ion beam. At the bottom, the ion tracks in the parallel oriented plate (the blurring at both ends of the trace is an artifact of the depth of focus of the microscope). False colors.

FIGURE 1. The tip of a 30,000-core optical fiber bundle is shown next to an Australian 5 cent coin for scale (left) and a zoomed-in image (right) reveals a small region of the fiber bundle facet (dashed red box in left). Each core is roughly 2 µm in diameter and separated from its neighbors by an average of 3.3 µm.

Fiber-optic Components: Fiber-optic bundles provide 3D stereo imaging

With each fiber acting as an independent pixel, coherent fiber bundles transmit more information than just a 2D representation of an image; specifically, the spatial light field faithfully encodes 3D stereo data.
