NIR710T - 710nm Near-infrared Absorbing Dye for Security & Optical Filters
NIR710T is a high-performance near-infrared absorbing dye with a sharp absorption peak at 710±2 nm within the 700–2000 nm NIR region. Its strong absorption originates from charge transfer within organic dye molecules, delivering precise spectral control with minimal visible‑light interference. This dye is widely trusted in anti‑counterfeiting systems, optical filters, and high‑temperature polymer processing applications.

Key Applications of NIR Absorbing Dye NIR710
1. Security Printing & Anti‑Counterfeiting
NIR710T produces invisible near‑infrared markers that are nearly undetectable under visible light but clearly identifiable with NIR readers. Common applications include banknotes, passports, certificates, luxury packaging, and brand authentication labels.
2. IR Cut‑off & Optical Filters
As an efficient IR absorber, NIR710T is ideal for IR cut‑off filters that block unwanted NIR radiation while maintaining high visible light transmission. Typically used in PDP displays, digital cameras, optical sensors, and imaging systems.
3. Temperature‑Resistant Injection Molding
The thermal stability of NIR710T enables safe incorporation into polymer processing workflows, such as injection molding of temperature‑resistant NIR‑absorbing plastic components, functional housings, and specialized parts.
4. Optical & Sensing Devices
NIR710T can serve as a functional additive in optical filters and NIR detection systems, supporting spectral selection, light management, and signal optimization in industrial sensors, analytical instruments, and smart optical devices.
5. Organic Thin‑Film Devices
With its well‑defined NIR absorption and solution processability, NIR710T is suitable for research and development in organic thin‑film ambipolar transistors and other next‑generation optoelectronic components.
