NIR815C Near-Infrared Absorbing Dye for High-Precision Optical & Laser Protection
NIR815C is a premium-grade near-infrared (NIR) absorbing dye engineered specifically for high-performance optical applications. Featuring a dark brown-red crystalline powder appearance, this specialized dye demonstrates exceptional light absorption functionality in the 700-2000 nm near-infrared region.
Unlike broad-spectrum absorbers, NIR815C provides highly targeted, narrow-band absorption, making it the material of choice for manufacturers developing laser safety eyewear, precision optical filters, and invisible security inks.
- Precise Absorption Peak (λmax): 815 ± 2 nm.
- Narrow-Band Profile: The sharp curve indicates targeted light capture without bleeding into the visible light spectrum, ensuring your end product maintains excellent transparency and avoids color distortion.
- High Molar Extinction Coefficient: Reaches maximum absorbance efficiently, meaning you need a lower concentration of dye to achieve the desired shielding effect, ultimately reducing your material costs.

Key Applications of NIR Absorbing Dye NIR815C
- Laser Safety & Protection: The 815nm peak makes it perfectly suited for absorbing emissions from specific diode lasers (e.g., 808nm/810nm systems). Widely used in manufacturing laser safety glasses, welding face shields, and inspection windows.
- Advanced Optical Filters: Blocks unwanted NIR interference while retaining true-color visibility, tailored for CMOS sensors, machine vision cameras, and analytical instruments.
- Anti-Counterfeiting & Security: Can be formulated into invisible security inks. The markings remain completely transparent in daylight but can be instantly verified using NIR detection equipment.
- Functional Coatings & Solar Films: Excellent heat-shielding properties when dispersed in polymer films (PMMA/PET) for smart windows or automotive thermal insulation.
- Biomedical Imaging: Utilized in scientific research for in-vitro fluorescence imaging, offering excellent tissue penetration with minimal background auto-fluorescence.
Why Choose NIR815C Dye?
- High Visible Light Transmittance (VLT): Effectively blocks near-infrared rays while allowing maximum visible light to pass through. Ideal for transparent optical panels and helmet visors.
- Superior Thermal and UV Stability: Formulated to withstand heat and continuous light exposure, delivering consistent performance in harsh industrial environments or outdoor applications.
- Industrial-Grade Purity: With ≥97% purity, it strictly prevents impurities from causing haze or scattering in optical films.
