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, White Opal and transparent polyester film 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.
