Ronchi Rulings / Gratings
APPLIED IMAGE precision
Ronchi Rulings are generated using our unique semiconductor pattern generator devices. The result is an extremely accurate ruling with smooth line edges and square edge-profile.
Standard rulings are available on optical grade soda-lime glass substrates, white opal glass, transparent polyester film or photographic paper. Rulings can be supplied on other materials such as B270, quartz or BK-7 glass as well as at other frequencies or sizes.
Contact APPLIED IMAGE for availability of rulings in English frequency metrics (Cycles per inch). An inventory is maintained of the following standard rulings.
