Abstract

In this paper, the effects of temperature on the refractive index layer of Magnesium fluoride, MgF2, is investigated. The 2 MgF layers, using the electron gun, in temperatures of different 25, 100, 200, and o 300 C were deposited on the glass substrate ( BK7 ). In all samples, the deposition rate was R  5 6 Å /C. Transmission spectra of samples, using a spectrophotometer at wavelengths 400 1800 nm were determined. The sample produced at room temperature was annealed for 2 hours at o 300 C. Then, indexes of refraction of samples were calculated using three methods. The refractive indexes according to the methods were in a good agreement with one another. The results showed that by increasing the temperature from laboratory temperature to o 300 C, the refractive index of Magnesium fluoride increased as a linear function from n =1. 32 to n =1. 39. Moreover, the index of refraction of the annealed sample increased conspicuously while the annealed sample showed some absorption.
