Spherical Lenses
REO's variety of fabrication capabilities includes a breadth of precision spherical lens manufacturing. Custom lens sizes and radius of curvature are available to serve your specific application. Our highly controlled processing of optical glasses from surface generation to coating minimizes subsurface damage and allows us to maintain pristine optical surfaces. This material and process control consistently results in high LDT lenses for all demanding applications.
Spherical polishing
REO polishes high performance spherical surfaces using both batch spindle polishing and CNC polishing techniques. Spindle polishing may be used to achieve the highest possible surface roughness, figure accuracy, and surface quality and is suitable for batches of smaller parts – for example up to 38 parts of 25mm diameter may be processed together. CNC polishing provides more efficient polishing of individual optics, and so is suitable for smaller batches and steeper radii of curvature.

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.
