Th e index of refraction of magnesium ox ide crystal has been m eas ured for \\'avrle ll gths from 0.36 to 5.35 microns. In the visible reg ion , measuremen ts were m ad e at t hree temperatures, close to 20°, 30°, and 40° C. Therma l coe ffi cients were computed fo r this range of temperat ures for n ine wavelengths.
