Device and process for preparing chalcogenide infrared glass material and method of device

Abstract

The invention provides a device for preparing a chalcogenide infrared glass material, and relates to the field of chalcogenide glass preparation, mainly aiming at reducing stripes in the chalcogenide infrared glass material through the device provided by the embodiment of the invention. The mainly adopted technical scheme is as follows: the device for preparing the chalcogenide infrared glass material comprises a frame, a worktable, a first lifting driving device, a melting furnace, a lower furnace door and a positioning device, wherein the worktable is mounted on the frame; the first lifting driving device is used for driving the worktable to move up and down; the melting furnace is rotatably mounted on the worktable; the melting furnace is provided with a furnace chamber and a first opening is formed in the lower end of the melting furnace; the lower furnace door covers the first opening and is detachably connected with the melting furnace; the positioning device is detachably connected with the lower furnace door, and used for positioning the lower furnace door and keeping the position of the lower furnace door unchanged when an external ampoule bottle is quenched. The device is mainly used for preparing the chalcogenide infrared glass materials.

Description

technical field [0001] The invention relates to the technical field of infrared glass manufacturing, in particular to a device for preparing chalcogenide infrared glass material and a process method thereof. Background technique [0002] Chalcogenide glass is a kind of non-oxide glass formed by introducing certain metal or metalloid elements Ge, Ga, As, Sb, etc., mainly composed of S, Se, and Te in the sixth main group elements (excluding O). The glass is an infrared transparent optical material with excellent performance. Chalcogenide has infrared transmission performance similar to that of single crystal germanium, and the transmission band covers three atmospheric infrared windows of 1-3 μm, 3-5 μm and 8-12 μm. The temperature coefficient of refractive index of commercial Se-based chalcogenide glass is less than 25% of that of single crystal germanium, and it has good light-thermal stability characteristics. The resource consumption of germanium is low, it can be formed...

Problems solved by technology

In a word, it is necessary to move the ampoule bottle during the quenching process. This movement inevitably causes the disturbance of the glass liquid level, resulting in the formation of uneven defects such as streaks in the glass product. The generation of these defects reduces the imaging quality of the optical system, and Increase the processing damage rate of optical components
