New State-of-the-Art Ruling Engine
for Ruled Diffraction Gratings Masters

ruled diffraction gratings engineAfter five years in development, OPCO has announced its NEXT GENERATION RULING ENGINE for the production of diffraction gratings masters. This new, state of the art ruling technology will permit OPCO to produce high quality replica gratings from new master rulings, quicker and less costly than traditional processes.

Most replicated ruled gratings produced today rely on masters created by decades old ruling engine technology; many of these masters were ruled more than 30 years ago. Because of our technologically superior mechanical design, OPCO’s replica gratings created from masters ruled on our new engine are demonstrating high efficiency, low scattered light, no periodic errors, and zero ghosts.

OPCO Laboratory welcomes your request for custom-ruled, high quality plane grating masters with virtually any groove frequency, blaze wavelength, and Dual Blaze.

All of OPCO’s gratings can be replicated for use in reflection or transmission onto a variety of glass, metal, ceramic, or polymer substrates. These replicas can then be coated with a high reflectivity coating for reflection gratings, or an A/R coating for transmission gratings.

OPCO’s proven replication process for gratings is repeatable and very cost effective. This ensures that the performance of the grating is equal to that of the master, and consistent from instrument to instrument.

Please contact us to discuss your spectrometer requirements and on how our replica gratings and assembly service can assist you in manufacturing a quality, reproducible spectrometer. Should you need assistance, our staff spectroscopist and optical designers are available to help you choose the right grating and optics for your application.
