Infrared Lenses
REO fabricates high precision infrared lenses from a variety of substrate materials, including fused silica, Si, Ge, ZnSe, ZnS, CaF2, MgF2 and Cleartran. Every aspect of the lens production process, from surface generation to the final coating application, is conducted using carefully controlled, advanced methods enabling REO to deliver lenses with minimal subsurface damage and pristine optical surfaces.
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.

Thin Film Coating
Over 20 years ago, REO became the first company to commercially provide Ion Beam Sputtered (IBS) thin film coatings. Today, we have expanded our technology to produce the highest quality thin films performing a range of functions across the full optical spectrum from the deep UV (190nm) through the long wave IR (14um). With a total of 35 coating chambers in operation, REO’s ability to produce the highest performance, lowest loss, most durable thin films across the spectrum is unmatched in the world.

Surface Metrology
REO maintains 14 Fizeau interferometers for accurate measurement of surface figure, utilizing several different configurations for both in-process and final product measurement of surface figure of flat and spherical surfaces. REO has interferometers at 633nm and 1064nm. These instruments normally have an absolute accuracy of approximately l/100. REO maintains interferometers with apertures of up to 150mm diameter, with lateral resolution of up to 100um.
