Cassegrain reflector, artwork C017 / 7061

Cassegrain reflector. Computer artwork of parallel beams of monochromatic light passing through a simple Cassegrain reflector. The light first hits a primary concave (converging) mirror (centre) and is reflected backwards to strike a small secondary convex (diverging) mirror (left). This mirror reflects the light back towards the primary mirror, where a gap allows the light to pass through and hit a focal point (right). Cassegrain reflectors are used in optical telescopes and radio antennas

EDITORS COMMENTS
This print showcases the intricate beauty of a Cassegrain reflector, an essential component in optical telescopes and radio antennas. Created through computer artwork, it depicts parallel beams of monochromatic light passing through this remarkable device. At the center of the image lies the primary concave mirror, which acts as a converging lens. As light first hits this mirror, it is reflected backward towards a small secondary convex mirror positioned on the left side. This diverging mirror then reflects the light back towards the primary mirror. A gap strategically placed within the primary mirror allows the light to pass through and ultimately hit a focal point on the right side of this composition. The symmetrical arrangement of mirrors ensures that all incoming rays are precisely focused at this central point. The black background emphasizes both simplicity and elegance while highlighting every detail in this physical illustration. The biconvex nature of these mirrors contributes to their ability to manipulate light effectively. With its classic design and precise engineering, this Cassegrain reflector serves as an indispensable tool for astronomers and scientists alike. Its parabolic shape enables optimal reflection and focusing capabilities, making it ideal for capturing celestial wonders or receiving signals from distant galaxies via radio antennas. Russell Kightley's artwork masterfully captures not only the technical aspects but also evokes a sense of wonder associated with exploring our vast universe using such advanced optical instruments like Cassegrain reflecting telescopes or hyperbolic reflectors.
