Infrared Emitter Tube/Lamp: Wavelength Range 850-1550 nm

Q: What is the difference between IR emitter tubes and lamps?

IR emitter tubes typically refer to semiconductor-based LEDs that emit narrowband IR through electroluminescence, while IR lamps are thermal emitters that produce broadband IR through resistive heating. LEDs offer faster response and precise wavelength control, while lamps provide higher power output and broader spectrum.

Q: How do I select the appropriate wavelength for my application?

Select based on your target material's absorption characteristics: 850-950 nm for general sensing, 1200-1400 nm for moisture detection, and 3000-5000 nm for thermal heating. Consider matching the emitter's peak wavelength to your sensor's or material's optimal response range.

Component Specifications

Definition

An infrared emitter tube or lamp is a specialized electronic component designed to emit infrared (IR) radiation within specific wavelength ranges, typically 700 nm to 1 mm. It functions as part of infrared emitter arrays in industrial equipment for applications such as non-contact temperature measurement, material drying, curing processes, IR spectroscopy, and proximity sensing. These components convert electrical energy into infrared radiation through semiconductor junctions (LEDs) or resistive heating elements (lamps), with precise control over emission characteristics.

Working Principle

Operates based on electroluminescence in semiconductor materials (for IR LEDs) or thermal radiation from heated filaments (for IR lamps). When electrical current passes through the semiconductor junction or resistive element, electrons recombine with holes (LEDs) or thermal energy excites atoms (lamps), emitting photons in the infrared spectrum. The wavelength and intensity are controlled by material composition, doping levels, current input, and operating temperature.

Materials

Semiconductor materials: Gallium Arsenide (GaAs), Aluminum Gallium Arsenide (AlGaAs), Indium Gallium Arsenide (InGaAs) for IR LEDs. Filament materials: Tungsten, carbon, or ceramic composites for IR lamps. Encapsulation: Epoxy resin, silicone, or glass with IR-transparent windows. Electrodes: Copper alloys with nickel or gold plating.
