High-Power SWIR LEDs for Gas Sensing and Optical Inspection

We specialize in high-power SMD infrared emitters for OEM and ODM optical systems. Our SWIR LED portfolio covers wavelengths from 1000 nm to 2060 nm and includes compact 3535 そして 5050 SMD packages for gas detection, 光学センシング, silicon wafer inspection, and related industrial applications.

For engineers developing a SWIR illumination or sensing system, selecting an LED is more than choosing a nominal wavelength. The final result depends on the interaction between the emitter, detector, optical path, filter, working distance, drive condition, thermal design, and target material or gas.

Our role is to help OEM teams evaluate these variables early, then define an SWIR LED solution that can be sampled, テストされた, and prepared for product integration.

SWIR LED Wavelength Range: 1000 nm to 2060 nm

Our high-power infrared LED solutions span the 1000–2060 nm spectral range. This range can support applications where selected SWIR wavelengths are used to identify material properties, support optical measurements, or illuminate features not easily distinguished under visible light.

The required wavelength should always be selected according to the application. For gas detection, wavelength selection depends on the target gas, optical path length, detector response, filter design, measurement method, and expected environmental conditions. For optical sensing or silicon wafer inspection, performance also depends on the material response, illumination geometry, imaging sensor, exposure time, and required contrast.

A nominal center wavelength alone is not a complete specification. A practical project specification should define:

• Nominal center wavelength
• Center-wavelength tolerance
• Spectral bandwidth or FWHM requirement
• Test current and measurement temperature
• Required optical output under defined operating conditions
• CW or pulsed drive condition
• Thermal limits and expected operating lifetime

3535 そして 5050 High-Power SMD Packages

Our SWIR LED emitters are available in 3535 そして 5050 SMD package formats. These compact package options are intended for systems where optical output, board-level integration, thermal management, and mechanical footprint must be balanced.

a 3535 または 5050 package is not automatically the better choice in every design. Package selection should account for available board area, thermal path, required drive current, optical design, mounting method, and illumination-area requirement.

For higher-output or larger-area illumination requirements, multiple SMD emitters may be evaluated in an array or multi-emitter configuration. Array design requires attention to current sharing, emitter spacing, thermal distribution, optical mixing, and irradiance uniformity at the target plane.

SWIR LEDs for Gas Detection

SWIR LEDs can be evaluated as compact optical sources for selected gas-sensing architectures. In a gas-detection system, the emitter wavelength, detector response, gas-cell design, optical path length, filters, modulation method, and signal-processing approach must work together.

A high-power SWIR LED may be relevant where an OEM system needs a compact, controllable, and potentially modulatable infrared source. しかし, a gas-detection result cannot be predicted from wavelength alone. Detection sensitivity, selectivity, response time, and calibration stability must be verified in the complete system.

Before sample selection, we recommend providing:

• Target gas or gas mixture
• Target measurement range
• Optical path length or gas-cell configuration
• Detector type and spectral-response range
• Filter requirements
• CW or pulsed operating mode
• Ambient-temperature and environmental conditions
• Required sample quantity and expected production volume

SWIR LEDs for Optical Sensing

Optical sensing systems may use SWIR illumination to examine moisture, material composition, coating behavior, surface condition, or other spectral features. The appropriate LED solution depends on the feature to be measured and the measurement geometry.

High-power SMD SWIR LEDs can be assessed for point sensing, reflective sensing, transmissive sensing, multispectral measurement, and other controlled-illumination designs. The engineering objective is not simply to maximize source output. It is to produce stable, usable signal at the detector under real operating conditions.

Important design inputs include target reflectance or transmission, working distance, field of view, ambient light, detector sensitivity, exposure time, optical filters, and required measurement repeatability.

Silicon Wafer Inspection and Imaging

SWIR illumination may be useful in silicon wafer inspection and imaging systems because silicon can exhibit different transmission and imaging behavior in the infrared range than in visible light. The best wavelength and illumination architecture depend on wafer thickness, feature type, inspection method, camera response, optical configuration, and throughput requirement.

For silicon-wafer applications, an engineering review should define the required inspection feature, detector type, working distance, illumination angle, field size, exposure time, and expected contrast. ハイパワー 3535 または 5050 SMD emitter may be evaluated as a component within a single-source, multi-source, or array-based illumination design.

CW and Pulsed SWIR LED Operation

Our SWIR LEDs can be evaluated for continuous-wave and pulsed operating conditions according to the application requirement.

CW operation may be suitable for steady illumination or continuous sensing. Pulsed operation may be useful for synchronized imaging, modulation, high-speed measurement, or controlled peak-output conditions. These modes must be evaluated differently.

A pulsed peak-output value is meaningful only when pulse width, repetition rate, duty cycle, drive current, and thermal conditions are stated. It should not be compared directly with a CW output rating. The final operating condition should be verified in the customer’s intended optical and thermal environment.

Engineering Samples and Project Evaluation

We support an engineering-led sample process for OEM and ODM programs. The appropriate sample plan depends on wavelength, package selection, drive mode, customization level, and application requirements.

A typical evaluation process may include requirement review, feasibility assessment, preliminary component selection, sample planning, optical and electrical testing, system-level validation, and production-specification discussion.

For meaningful evaluation, please provide your target wavelength, detector type, working distance, optical geometry, operating condition, thermal constraints, and expected annual volume.
