We indicate the blaze angle (a) which is given by the formula:
2a sina = klB, where a is the groove spacing, k is the diffraction order (usually k=1) and lB is the blaze wavelength (in Littrow configuration).

Ruled area: extends to within a 2-4 mm border around the grating edge

Standard substrate material is Pyrex; on request, substrates including fused silica, Zerodur, ULE, metals, or other materials can be considered.

Standard coating is aluminium. On request, AlMgF2, gold or platinum are also available for an additional cost.
