Esco continues to invest in cutting edge technology. Most recently, we've added two Optotech CNC lens machines to our existing four, which allows us to produce a variety of spherical, cynlindrical, and aspherical radius work.

Three axis CNC milling machines allow Esco to shape and step windows, while double-sided lapping and polishing machines ensure high commercial or precision quality windows in large quantities.

Our in-house coating department is made up of four chambers. Our box coater is ideal for large volume, anti-reflective work, and our smaller chambers specialize in Neutral Density, Metallic, and Dielectric coatings.

For extreme precision, the pitch polishing department includes single-sided lappers and polishers and two Zygo interferometers to ensure our work is accurate and that you are satisfied with the final product.
