Designed for use in first order, Newport's Richardson Gratings, are blazed for specific wavelengths and generally have high efficiency at those wavelengths. Flexibility in substrate material, size and coating type allow you to build the grating for your system.
Ruled gratings comprise the majority of diffraction gratings used in spectroscopic instrumentation. At Newport, we have three ruling engines in full-time operation, each producing high-quality master gratings each year. These ruling engines provide gratings with triangular groove profiles, very low Rowland ghosts, and high resolving power. Mechanically ruled, individual grooves are burnished with a diamond tool against a thin coating of evaporated metal. Utilizing a high fidelity cast replication process, developed and enhanced through years of research and manufacturing experience, we have the ability to provide duplicates of master gratings that equal the quality and performance of the master grating.
Typically used in systems with collimated, incident light, plane ruled gratings require auxiliary optics, such as lenses or mirrors, to collect and focus the energy. Our Diffraction Grating Handbook provides a description of standard grating mounts, such as the Czerny-Turner Monochromator. |
