01 / OVERVIEW

Flat mirrors for optical path control

A flat mirror is a reflective optical component with a planar surface designed to redirect light without introducing focusing power. Optical flat mirrors are commonly used for beam steering, optical path folding, interferometry, and imaging systems where accurate reflection and controlled wavefront performance are required. Surface flatness and reflective coating performance are therefore important factors in maintaining beam quality and system accuracy.

Strahl Optics focuses on maintaining controlled planar geometry and surface consistency throughout flat mirror production. Our fabrication process combines precise surface finishing with reflective coating control to support stable wavefront quality and reliable reflection performance.
