Infrared transparent gallate glass

Abstract

This inventive infrared ray transmitting glass (gallate glass) is composed of (by mol percentages): Ga2O3:5-40, MO / MCO3:30-70,MF2 / MCl2:0.1-25,Me2O3:0-24. During the smelting, introduced are: dry air, CC14, GeC14, C12, SOC12, one or more of these kinds, to effectively lower the harmful content of hydroxyl. The glass has its cut-off wavelength longer than 6um, and has advantages of: low glass phonon energy, better glass formation property, excellent mechanical property, high optical quality, low hydroxyl content, suitable for making plane sensor window, scout plane window, automobile window, head cover of missile, optical fiber of infrared ray laser, substrate glass of optical fiber amplifier.

Description

Infrared gallate glass technical field The present invention relates to optical glass, especially a kind of infrared gallate glass. The over-spectral effect is small. Background technique Optical materials with high transparency in the 0.5-5μm band have very important applications in civilian and military fields, including: infrared countermeasures (IRCM), chemical remote sensing, laser radar, infrared target simulation, secure space communication and satellite communication, infrared guidance, aviation - space reconnaissance instruments and so on. These new-generation optoelectronic systems often work under very harsh conditions, so higher requirements are put forward for their window materials, not only hope that they have as low as possible light absorption and high laser damage threshold in the infrared laser emission band And optical uniformity, etc. At the same time, there are often higher requirements for material size (>φ200mm), molding, mechanical and thermal...
