threeCCD
ThreeCCD is a type of astronomical camera system that uses three charge-coupled devices (CCDs) to capture images of the night sky. Each CCD is sensitive to a different range of wavelengths, allowing the camera to capture a broader spectrum of light than a single CCD. The three CCDs are typically arranged in a triangular pattern, with each CCD covering a different part of the spectrum. The system is designed to capture images in the ultraviolet, visible, and near-infrared ranges, providing a more comprehensive view of the sky than traditional single-CCD cameras. ThreeCCD cameras are often used in astronomical research, particularly for studying the properties of stars and galaxies. They are also used in space-based telescopes, such as the Hubble Space Telescope, to capture high-resolution images of distant objects. The system's ability to capture a broader spectrum of light makes it a valuable tool for astronomers studying the universe.
