05 Aug 2022 LASER COMPONENTS represents Optometrics in the UK, supplying wavelength selection solutions including diffraction gratings, monochromators, optical filters, and tuneable light sources. Amongst the comprehensive range of diffraction gratings offered are Echelle replica gratings. Echelle gratings are special low period gratings designed for use only in high orders. Although the maximum resolution is obtained, it is generally necessary to use a prism or a second grating to separate overlapping diffracted orders. Echelle gratings are an ideal solution for high-resolution spectroscopy due to their high dispersion in high orders.
We provide a range of standard diffraction gratings, and have extensive custom capability to offer gratings tailored to specific applications.
