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 | |
