2835 Far‑Infrared LED
The 2835 far‑infrared LED series is designed with SMD packaging and operates within the 1000–1600 nm wavelength range. These LEDs provide stable radiant output suitable for heating‑related equipment, drying systems, and controlled thermal environments. Their compact footprint supports easy integration into industrial devices and modular assemblies.
Multiple peak wavelengths and radiant‑intensity levels are available, allowing engineers to select the appropriate configuration for different material characteristics and process requirements. The series supports applications ranging from small‑scale moisture‑control enclosures to continuous drying lines.
