... Thus all regions of the 0.94-2.50 micron wavelength range accessible from Mauna Kea can be recorded using five fixed angle gratings. ... Grating Angle . ... Efficiencies for the NIFS gratings are shown above. The NIFS spectrograph uses a Bouwers collimator and a refractive camera. ... With these assumptions, the NIFS system efficiency including the Gemini telescope optics but excluding the transmission of the adaptive optics system is about 0.17 e - /photon at J , and 0.22 e - /photon at H and K . ...
