Study on crystal growth and transmittivity of large-size KBr |
| |
| Abstract: | The factor of affecting crystal transmitivity and absorptance was analyzed and rational technological parameters were designed and high transmittivity potassium bromide (molecular formula :KBr) single crystal of 150mm in diameter and 150mm in length was grown by Czochralski method. Transmission spectra of KBr indicated that its transmittivity was about 80% in the rang of 0.3-34μm wave length. The reason of causing scattered particles was analyzed. |
