A parabolic mirror has a reflecting surface forming a paraboloid of revolution. A point source at its focus produces reflected rays parallel to the principal axis; conversely, parallel rays converge at the focus. This geometry serves efficient light collection or collimation in headlights, searchlights, satellite antennas, reflecting telescopes, and solar concentrators. An off-axis parabolic mirror places the focus away from the optical axis, avoiding obstruction and improving compactness and flexibility. The source states that it focuses without chromatic aberration, phase delay, or absorption loss, suiting femtosecond lasers and infrared use. Dongkeda offers uncoated and coated mirrors, including standard protected aluminum, protected UV-reflecting aluminum, and protected gold. Metallic coatings generally meet instrument needs; multilayer dielectric coatings increase reflectance and reduce absorption loss when higher performance is required.
