Advantages:

Wavelength Range: 4000nm–4500nm (Mid-Wave Infrared, MWIR)

• Emits mid-infrared radiation, ideal for molecular absorption spectroscopy, especially in gas sensing.
• Covers strong absorption lines of various gases like CO (Carbon Monoxide), CO₂ (Carbon Dioxide), and CH₄ (Methane).

SMD 2835 Package (Surface-Mount Device)

• Compact and efficient design;
• Compatible with reflow soldering;
• Allows dense sensor arrays and miniaturized systems.

Lead-Free (RoHS Compliant)

• Environmentally friendly and safe for use in modern electronics manufacturing.

Narrow Emission Spectrum

• Optimized for selective gas detection using non-dispersive infrared (NDIR) techniques;
• Enables accurate sensing by matching the peak wavelength of target gas absorption bands.

Stable Output & Long Life

• Designed for continuous operation in industrial and field applications;
• High reliability for demanding environments.

Efficient Thermal Management

• Tailored to maintain consistent performance even under extended use or higher drive currents.
