Description
D-shaped mirror is always used to separate closely spaced light beams. The high reflective coating extends to the straight edge of the mirror within 0.05mm, and a portion of the substrate behind the straight edge is removed, these make D-shaped mirror is ideal for picking off one of two closely spaced light beams, and not affect the beam which is not picked off.
