Standard replicated gratings are produced from ruled and holographic originals and are intended for use in moderate resolution spectrophotometers, spectrometers and monochromators where low cost, high efficiency and low stray light are of primary concern. Since standard gratings are cut from larger replicas, they are ruled over their entire surface. Incident radiation should, however, be restricted to 90% of the ruled area.

High Resolution Ruled Gratings

Replicating master gratings on Pyrex®, produces gratings with flatness, λ/4 or better, good thermal stability and resolution equal to 80-90% of the master. High resolution gratings are available in groove spacings from 120 to 1800 g/mm, blazed from 240 nm to 12.0μ. For even better thermal stability, ask for a quotation for gratings replicated on Zerodur®.
