Optical Glass Gratings

Product catalog summary

Overview: The document provides detailed information on optical glass gratings, linear scales, discs, glass plates, and reticles, focusing on their specifications, materials, and applications.

Optical Glass Gratings: These are available in various configurations and are used in customized measuring or detection systems. They are made of vacuum-deposited chrome on a glass substrate, ensuring high accuracy and resistance to chemical and mechanical abrasion. Gratings can include incremental and absolute tracks with reference marks.

Materials and Specifications: Glass substrates come in different lengths, widths, diameters, and thicknesses, made from materials like float glass, BK7 optical glass, quartz glass, ceramics, borosilicate, and aluminum oxide. The thickness ranges from 0.5 to 8 mm, with coatings like vacuum-deposited chrome.

Linear Scales: These scales can be up to 3400 mm in length and are processed through scribing, breaking, and laser cutting. They offer high accuracy with edge linearity up to 0.015 mm/m.

Discs and Reticles: Made from ground and polished glass, these components are processed through laser cutting and grinding, ensuring edge linearity of 0.015 mm/m.

Glass Plates: Available up to 8 inches in size, with a minimum element size of 5 µm. They are coated with materials like aluminum, silica, and chrome, offering a maximum graduation accuracy of 2 arc seconds.
