Applications

Optical Sensors & Detection Systems
GLS424P enables precise 424nm absorption for biomedical sensors, environmental monitors, and industrial process control.

Anti-Counterfeiting Ink & Security Marking
Creates covert features detectable under 424nm illumination for machine-readable authentication of banknotes, passports, tax stamps, and luxury goods.

Optical Filters & Light Control Films
Blocks unwanted 424nm light to improve image clarity in cameras, displays, and optical instruments. Ideal for band-stop filters that reject violet-blue light while transmitting other visible wavelengths.

Precision Optical Components
Used in fiber optics, waveguides, and micro-optical devices requiring precise short-wavelength visible light control.

Violet-Blue Light Rejection for Displays
Enhances contrast and color purity in LCD/OLED displays by selectively rejecting eye-straining violet-blue light.
