Abstract

PURPOSE:To manufacture an IR-transmitting glass having improved thermal stability and transmitting characteristics, by using a quadri-component material obtained by compounding ZrF4, BaF2, NaF and YF3 at specific ratios. CONSTITUTION:An IR-transmitting glass containing 53-61mol% ZrF4, 18- 27mol% BaF2, 10-25mol% NaF, and 1-6mol% YF3 wherein the sum of the above four components is 95-100%. Since the glass has large temperature difference between the glass transition temperature and the crystallization temperature, and is thermally stable, it can be cast to a block having a large thickness. It has excellent light transmitting characteristics such as high transmittance of light from the visible light to the IR ray of about 8mum wavelength and a flat transmitting spectrum. The galss is useful as the material of window or lens of an infrared apparatus or a material of an IR-transmitting optical fiber.
