A parabolic mirror is a reflector made of silvered glass or metal with a parabolic axial cross-section. When a light source is placed at its geometrical focus, the mirror reflects the light into nearly parallel rays, producing uniform and directional illumination.
Parabolic mirrors are commonly used in studio lighting, optical instruments, and photography to create strong, focused lighting with minimal diffusion. Their precise shape allows for controlled highlights, dramatic shadows, and efficient use of light, making them valuable tools for photographers and lighting designers.
