With the rapid development of global industrial demand and application technology, the user market's pursuit of product quality has also been rising, even to the point of being demanding and picky. So how do we judge and choose products with good thermal imaging quality?

In the modern electronic optics industry, most of the imaging lenses used for thermal imaging are chalcogenide glass. Chalcogenide glass is cheap, low cost, low quality, easy to demold and break, and has a short warranty. The Onick RE640 binocular thermal imaging is made of all-germanium lenses. The production process of all-germanium lenses is very complicated. The germanium dioxide is reduced to germanium crystals in a reduction furnace, and then the crystals are pulled in a crystal pulling furnace after cleaning and purification. Then, a series of processes such as cutting, rough processing, fine processing, grinding, and coating are carried out. Each lens is polished out bit by bit.

In addition, the Onick RE640 binocular thermal imaging adopts a carbon film on one side and an anti-reflection film on the other side. The hardness of the carbon film is very good to improve the protection of the lens. The anti-reflection film improves the transmittance of the lens. The transmittance of the lens with a carbon film on one side and an anti-reflection film on the other side can reach 93%.

Now many users are confused about the principles of thermal imaging of germanium and chalcogenide glass and infrared technology. In fact, although both technologies use infrared spectrum for imaging, their imaging principles are very different. Therefore, the quality of all-germanium lenses is harder and stronger than that of chalcogenide glass, with a longer service life, strong durability and high light transmittance.

Secondly, the onick RE640 binocular thermal imaging is a high-quality product produced by using internationally advanced high-sensitivity uncooled infrared focal plane detectors, excellent imaging circuit components and optimized optical systems, and is designed according to scientific ergonomic structure. The product uses a high-resolution infrared sensor, with infrared imaging effects, international ultra-low power consumption, fast startup, simple operation, compact and stable structure, and can be used for handheld or fixed observation, night reconnaissance, evidence collection and target search, and has photo/video evidence collection functions, which can record video images for a long time. The product uses a single built-in rechargeable battery and can work continuously for up to 6 hours. In addition, it has advanced fast startup performance, and the image will not be interrupted or frozen due to correction operations, which significantly improves the user's ability to respond quickly. The product is designed and manufactured according to military standards and can be used in harsh battlefield environments.
