Following our philosophy of innovation and our commitment to new technologies, Mecanizados Escribano, has started a new line of Precision Optics Manufacturing. With this new line we increase our service capabilities for our customers.
The manufacturing capabilities we possess include nano-turning equipment with diamond tools. These techniques allow carving spherical and aspheric surfaces, widely used in optical design. Although manufacturing limits vary from one configuration to other, we can obtain precision specifications in shape of 1/20 λ per centimeter. The typical roughness range is 40-120 angstrom of RMS, depending both on the material and the configuration.
As in every high precision manufacturing, an extremely strict quality control is necessary. For this purpose, at Mecanizados Escribano, we have increased our metrological capabilities with the acquisition of interferometric equipment. We have a white light interferometer microscope for measuring roughness with a vertical resolution accuracy smaller than 0.1 nm and an interferometer system with a Fizeau configuration for measuring shape errors with a resolution of λ/8000. We also have a contact profile meter with an accuracy of 0.8 nm assessing on one single measurement the size and texture of the surface
