Ref index/wavelength data for GaSb & InSb at 2-20um

  1. Mar 23, 2015 #1
    I need to obtain refractive index vs wavelength data for the following materials:

    GaSb (Gallium Antimonide)
    InSb (Indium Antimonide)

    For the range from 2μm up to ideally 20μm but up to 10μm would do.

    Looking on the two websites I know of for sourcing such data:


    But these websites only have values up to 1-2μm.

    Where can I find data for larger wavelengths?

    Have a look at this article http://www.researchgate.net/profile/Ali_Reshak/publication/226769627_Calculated_optical_properties_of_GaX_%28XP_As_Sb%29_under_hydrostatic_pressure/links/0912f50d0b1a322c54000000.pdf [Broken]
