The difference between short wave infrared, near infrared, medium wave infrared and long wave infraredNear Infrared (NIR): Wavelength between 0.75-1.4 microns, defined by the absorption of water, usually used in optical fiber communication due to the low attenuation rate in silica glass. Wavelengths Read More

The company's main products include infrared lenses, night vision objectives lens and other customizable optical lenses. It is mainly suitable for scenarios such as thermal imagers, infrared sights, night vision, infrared cameras, and drone monitors. Read More

The athermal lenses mainly realizes the day-night conversion through the infrared filter, that is, opening the filter in the daytime to block the infrared rays, so that it can only sense the visible light. In the case of night vision or poor lighting conditions, the filter will stop working, and the Read More

Chalcogenide glass is gradually replacing germanium for mass‑produced infrared lenses. Germanium suffers from high cost, supply constraints and thermal drift. With low‑cost molding, good athermal performance and mature coating solutions, chalcogenide glass meets most civilian and industrial optical requirements. Germanium remains essential for high‑end military and long‑range detection, creating a differentiated market layout. Read More

Brief Introduction Infrared lenses cover a wide price range from entry-level civilian models to high-end industrial and professional-grade products, with a price gap of dozens of times. To most users, these lenses look visually similar in shape and structure, but deliver completely different imaging effects, temperature measurement accuracy and service stability. Unlike conventional visible-light lenses that support mass low-cost production, infrared lenses rely on exclusive infrared-transparent materials, precision coating technology and professional optical optimization. The huge price difference is not caused by brand premium, but by systematic differences in materials, craftsmanship, environmental adaptability and precision calibration. This article systematically analyzes the core cost factors behind infrared lens grading. Read More
