Scales and Reticules

Product catalog summary

Overview
Fratelli Rotondi specializes in the production of optical scales and precision gratings, essential components for machine tools, measuring machines, and various operating machines. The company emphasizes the importance of engraving accuracy and raw material selection to ensure high-quality and reliable products.

Optical Scales
Optical scales are crucial for defining axis translation in machines. They are available in glass and steel, with specifications tailored to customer needs.

Glass Optical Scales: Maximum length of 3200 mm, made from float glass with a planarity of 10 µm/100 mm, chrome coating treatment, and accuracy of ≤ 3µm/1000 mm.
Steel Optical Scales: Maximum length of 100 meters, made from tempered AISI 420, with a planarity of 3 µm/100 mm, and accuracy of +/- 3µm/1000 mm.

Precision Gratings
These are designed based on customer requirements and are used in various sectors such as aerospace, microscopy, and optoelectronics. The production occurs in a controlled environment to ensure high accuracy and quality.

Substrate Options: Includes float glass, soda lime, borofloat quartz, and others.
Surface Treatments: High to low reflective chrome, anti-reflection coatings, and more.
Dimensions and Accuracy: Standard up to 16” (400 mm), with pattern accuracy of +- 0.001 mm and minimum pattern dimensions of 0.002 mm.

Applications
The products are applicable in sectors such as CNC machines, machine tools, positioning systems, and high-resolution displays. The company supports customers in finding the best solutions for their specific applications.

Optical Scales The optical scales are the main components for machine tools, measuring machines and general operating machines. This is the system that defines the correct axis translation. Together with the integration of his own electronic system the customer is able to build up a complete measuring system. The engraving accuracy of the pattern on the substrate defines the accuracy of the whole machine. Our Company is equipped with metrological rooms with controlled environment conditions. We are able to produce incremental, coded and absolute scales both with standard and customized pattern....
