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 using our unique manufacturing capabilities and process technologies. The standard rulings are in Metric frequency metrics (cycles per millimeter) on optical grade soda-lime glass or photographic paper.
The Ronchi rulings are available on other substrate materials such as B270, quartz, BK-7, and White Opal as well as in English frequency metrics (cycles per inch).
Contact the APPLIED IMAGE Sales Department for pricing and availability on these rulings and other unique frequencies.
