Collimating Optics for CO2 Laser and IR Optics Systems

Reflective and transmissive collimating optics are used in beam delivery systems to maintain beam collimation between the laser resonator and the focusing optics. Reflective collimators typically use Cu total reflectors, while transmissive collimators typically use ZnSe lenses.
