GLS606 Applications

Optical Filters & IR Cutoff Films

GLS606 is widely used in the production of optical filters and IR cutoff films for display panels, camera lenses, and automotive sensors. It effectively blocks 606nm orange-red light and near-infrared radiation, improving image quality and reducing glare.

Anti-Counterfeiting Ink & Security Printing

Used in anti-counterfeiting inks and security printing, GLS606 creates covert marks that are invisible to the naked eye but detectable with 606nm light detectors. This makes it ideal for high-value products, certificates, and packaging, enhancing security and preventing counterfeiting.

Display Materials & Optical Components

Suitable for display materials such as LCD screens, OLED panels, and LED displays, GLS606 helps control light transmission and improve color accuracy. It is also used in optical components such as lenses and prisms to enhance performance.

Laser Protection & Welding Goggles

As a 606nm absorber, GLS606 is used in laser safety filters and welding goggles to protect the eyes from harmful 606nm laser radiation. It maintains clear visibility while blocking dangerous light, ensuring safe operation.

Engineering Plastics & Transparent Coloration

Compatible with PC, PMMA, and other engineering plastics, GLS606 provides transparent, uniform coloring for automotive parts, optical lenses, and consumer electronics. It maintains stability during high-temperature processing, ensuring consistent color and performance.
