Esco Optics is a leading manufacturer of optical components in the United States as well as military and defense optics. From prototypes to high volume production, Esco can manufacture custom optics to meet all your requirements.

Our diverse production shop and highly-trained staff allows us to manufacture an extensive catalog of over 2,000 optical components. By maintaining a large inventory of raw materials, we can quickly and efficiently produce our own blanks. This helps cut down on lead time, so you receive your order in a shorter amount of time, as compared to our competitors.

We also have the ability to manufacture custom precision optics. We own a variety of CNC machines, on-site double-sided lapping and polishing, and our own coating lab that offers anti-reflective, dielectric max reflector, and metallic reflector coatings. By investing in the latest technology, we can easily meet all of your needs.
