New dispersive elements providing relative high resolution (R=2200) have been recently incorporated in the near infrared spectrograph LIRIS. These elements are founded on a rather novel design based on a diffractive pattern engraved in fused silica, which is placed between two prisms. These new components are pushing forward the scientific capabilities of the instrument by enhancing the medium resolution spectroscopic mode of operation. Details on the design, specifications and measured performances, as well as aspects related to the integration and astronomical tests in the instrument are presented.
