03 Jul 2023 LASER COMPONENTS supplies optical diffraction gratings for the UV, visible and near infrared range. Standard replicated gratings are produced from ruled and holographic originals and are intended for use in moderate resolution spectrophotometres, spectrometres and monochromators where low cost, high efficiency, and low stray light are paramount. Since standard gratings are cut from larger replicas, they are ruled over their entire surface. Replicated gratings meet or exceed the performance characteristics of the originals.
High resolution first order gratings are offered on Pyrex substrates with a surface flatness of l/4 or better, good thermal stability, and a resolution equal to between 80% and 90% of the master. High resolution gratings are available in groove spacings from 120 to 1800 g/mm, blazed from 250nm to 12.0µm. For even better thermal stability, gratings can be replicated on Zerodur.
Diffraction gratings are available for quick delivery for low volumes and can be produced in very large annual quantities.
