01 / OVERVIEW

Concave mirrors for reflective focusing

Concave mirrors are curved reflective optical components designed to collect, focus, or collimate light through a controlled surface profile. Unlike refractive lenses, focusing concave mirrors operate by reflection and therefore do not introduce chromatic aberration, making them suitable for optical systems that require broadband or wavelength-independent focusing performance.

Concave mirrors are available with spherical, parabolic and other surface profiles to support different focusing and collimation requirements. Our manufacturing workflow focuses on precise curvature control and surface finishing, then matches the reflective coating to the required wavelength range and optical performance.
