Frequently Asked Questions

The blaze angle of the ruled plane gratings is given by the formula: 2a sinα= kλB, where a is the groove spacing, k is the diffraction order (usually k=1) and λB is the blaze wavelength (in Littrow configuration).

The efficiency performance of the ruled plane gratings varies depending on the model. Efficiency curves are provided for reference only and do not indicate grating specifications.

The standard substrate material is Pyrex, but substrates including fused silica, Zerodur, ULE, metals, or other materials can be considered upon request.

Ruled plane gratings are used in monochromators, spectrographs, Raman spectrometers, spectroscopy, and beam isolation.

The dimensions of the high-precision replica gratings typically range from 25x25 mm up to 120x140 mm.
