General Optics

Plano and Spherical Mirrors

Reflect high-power laser beams within laser resonators and in external beam delivery systems with these durable, stable optics.

Coherent manufactures plano and long radius spherical laser mirrors for both intra- and external cavity applications. These are available with a variety of substrates, diameters, and coating options to meet the needs of nearly any application.

Plano and Spherical Mirrors Selection

Select from silicon, which combines low cost, good durability, and thermal stability - copper for high-power applications – and molybdenum for unmatched durability.
