Diodenlaserabsorptionsspektroskopie
Optical multiplexers may use any of several technologies to accomplish the mux/demux function. However,
echelle grating-based muxes are advantageous in that they may be incorporated into a very simple and compact design.
Echelle gratings are relatively course diffraction gratings that operate in orders other than the first order with blaze angles
typically greater than 45 degrees. The course line spacing on the grating combined with high order operation results in
a large angular dispersion that allows the device to be compact

I'm not well conversant in this technology and can't find helpful references quickly, but it looks to me like the publication is correct and the patent is not. Note that in the preceding sentence the same error/discrepancy exists.
