CO2 Mirrors
Copper reflectors are ideal for beam delivery and beam shaping with high power CO2 lasers. In particular, these mirrors offer a combination of high reflectivity, >99.7% at 10.6 μm, excellent surface quality (40-20) and low scatter with surface roughness <50Å. Produced from OFHC (oxygen free, high thermal conductivity) copper, these reflectors deliver superior optical performance and maximum laser damage threshold. These CO2 laser mirrors can be fabricated with plano, spherical or cylindrical surfaces and can range from 6 mm to 150 mm in size.
Diamond Turning
Single Point Diamond Turning is a technique for producing optical quality surfaces using a lathe configuration with a diamond-tipped tool. A primary advantage of this technique is the ability to produce complex aspheric surfaces efficiently. It is generally suited to metals and softer crystalline and amorphous optical materials such as ZnS, ZnSe, Ge, Si, and CaF2. The technique can be used to produce rotationally symmetric and off-axis aspheric optics, diffractive optics, and even non-rotationally symmetric optics such as cylinders.

High Laser Damage Threshold Optics
REO consistently delivers optics with exceptional laser damage resistance characteristics because we fabricate, coat and laser damage test our products under highly controlled processes in our state of the art facility in Boulder, CO. REO is unique because of our broad well-equipped in-house laser damage testing lab with several different laser pulsewidths and wavelengths. This vertical integration is critical because reliably achieving high damage threshold requires careful control over every aspect of the design and manufacturing process. This includes precise specification and thorough inspection of incoming raw materials, followed by shaping and polishing of components in a way that minimizes subsurface damage and contamination. We then design and deposit thin film coatings using techniques that avoid contamination and minimize electric field effects.
