ZGJC IRG Chalcogenide Glass range offers high precision lenses for mass volume production, while the extremely hard and scratch-resistant Sapphire can be customized to your exact specification.
The main component of chalcogenide glass is one or more of the chalcogen elements S, Se and Te. It has high transmittance to the infrared band of 8~12 microns, which can quickly and accurately measure the human body temperature. The temperature range is -20 ℃~+120℃, temperature measurement accuracy can reach ±0.3℃.
The infrared lens can perform multi-point body temperature detection for people who have passed the inspection, without close contact, and only need to be separated by 3 meters to 4 meters to accurately and efficiently screen the passing people.
And through the thermal imager to detect the extremely small temperature difference, the temperature difference is converted into a real-time video image to display, and immediately alarm when the body temperature is high, and quickly and safely identify feverish people.
IRG Chalcogenide Glasses
When common IR materials have reached their limits, IRG supports demanding applications in terms of cost, performance and processing power. These glasses encompass the common IR transmission bands 3-5 μm and 8-12 μm, but are able to transmit as low as 0.7 μm.
CHARACTERISTICS
The IR glass series offered by ZGJC can also be processed using conventional grinding and polishing techniques, as well as single point diamond turning or molding to support low- to high-volume manufacture.
Chalcogenide glass (far-infrared glass) has good transmittance, extremely low refractive index temperature thermal coefficient and dispersion performance due to its special structure and composition. It can be used in conjunction with other infrared materials for chromatic aberration correction, In the infrared optical system without thermal defocus.
It becomes an ideal material for optical designers to design optical systems without chromatic aberration and thermal defocusing.
Since the glass material can be molded into preforms or directly precision molded, it is the best choice to reduce processing costs for products in batches.
Chalcogenide glass is mainly used in 8～14μm infrared detection instruments and equipment.
It can be processed into aspherical far-infrared optical condenser lens, far-infrared spherical lens assembly, far-infrared prism assembly, far-infrared glass window, and can also be used as substrate material for epitaxial GaAs, GaN, and InGaN semiconductors.
Chalcogenide glass is used as a more conventional infrared material in fields such as vehicles, infrared monitoring, thermal imaging, acousto-optic components, optical communications, and mid-to-far infrared laser transmission.
Chalcogenide glass is an important part of national defense, inspection, monitoring, laser industry, and communications.
