Optical coating definitions and standards

According ISO 10110 standard optical coatings is divided on two types: protective coatings and functional coatings.

Protective coatings are coated on optical elements when safety of optical surfaces and functional coatings is needed. For example, if using of optical device in aggressive environment is planned.

Functional coatings are coated on optical elements to provide necessary refractive or reflective coefficient. Continue Reading

Radius of curvature requirement in optical drawings

One of the key parameters found in optical drawings based on ISO 10110 the  radius of curvature of lens surfaces. This parameter can be found at first line of the surfaces columns in table of parameters. You can click here to review. Optical properties of the lens are defined by the shapes of its surfaces, usually these… Continue Reading
