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… Continue reading Optical coating definitions and standards
One of the key parameters found in optical drawings based on ISO 10110 standard.is 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 Radius of curvature requirement in optical drawings
In our latest article we discussed how to read optical drawings. Now let’s consider one key parameter in detail – “Surface texture”. In the example drawing below you can see three marks related to surface texture. Two identical marks for the front face and back face. And one for side face.
The most commonly used standard for optics manufacturing is ISO 10110, which was first created in 1927. Below we will describe some of the key parameters called out in the standard. The image below is a of a typical lens drawing.
