Chinese SWIR LED Exporter for 1000–1900nm Applications

Quick Answer

Yingfeng is a Chinese manufacturer and exporter of SWIR LED emitters, COB assemblies and custom LED modules for industrial sensing, machine vision and spectral analysis.

Our SWIR product range covers approximately 1000nm to 1900nm, with options for different wavelengths, SMD packages, chip sizes, viewing angles and optical output levels. Custom configurations can be evaluated according to the target material, detector, working distance and production requirements.

SWIR LEDs Manufactured and Exported from China

SWIR, or short-wave infrared, covers wavelengths beyond conventional 850nm and 940nm infrared illumination.

Materials such as water, plastiques, silicon, oils and organic compounds exhibit different absorption or transmission characteristics in the SWIR region. When paired with an InGaAs camera, photodiode or spectrometer, SWIR LEDs can support industrial inspection and material-identification systems.

Yingfeng supplies SWIR LED products to international equipment manufacturers, optical-system developers, research institutions and machine-vision integrators.

Available SWIR LED Wavelengths

SWIR products and custom projects may cover wavelengths including:

These applications are general engineering directions. Actual performance depends on the sample, detector response, optical filter, working distance, environment, calibration and algorithm.

Specific wavelength availability, binning tolerance and optical output must be confirmed for each project.

SWIR LED Product Options

Yingfeng can evaluate requirements for:

• SWIR LED emitters
• SMD SWIR LED packages
• 3535 and other package formats
• High-power SWIR LEDs
• Custom center wavelengths
• Wavelength binning
• Different LED chip sizes
• Custom lenses and viewing angles
• Multi-chip LED packages
• SWIR COB assemblies
• SWIR LED PCB assemblies
• Custom SWIR LED modules

Each product should be selected according to the required wavelength, radiant power, radiant intensity, spectral width, viewing angle, drive current and thermal conditions.

Applications

Vision industrielle

SWIR illumination can reveal material differences that are difficult to distinguish under visible or standard near-infrared light.

Moisture Detection

Wavelengths near certain water-absorption bands can support moisture inspection in food, agricultural products and industrial materials.

Plastic Sorting

Different polymers may present different absorption characteristics in the SWIR region, supporting automated sorting and recycling systems.

Silicon and Wafer Inspection

Silicon becomes more transmissive at wavelengths beyond the visible and conventional near-infrared regions. A suitable SWIR LED and camera combination can support semiconductor inspection.

Food and Agricultural Inspection

SWIR illumination can contribute to the inspection of moisture, bruising, foreign materials and composition differences.

Spectroscopy and Optical Sensing

Narrow spectral bands can be used as compact light sources in photometric and spectroscopic instruments.

Custom SWIR LED Export Services

International customers can submit a custom requirement that includes:

• Target wavelength
• Wavelength tolerance
• Required optical output
• Detector or camera model
• Continuous or pulsed operation
• Working distance
• Illuminated area
• Viewing angle
• Package or PCB dimensions
• Prototype quantity
• Estimated annual demand

Based on this information, Yingfeng can evaluate the LED die, emballer, optics, PCB, thermal structure and production process.

Quality Information Available for Evaluation

Depending on the selected product and project stage, customers may request:

• Product datasheet
• Spectral distribution data
• Electrical and optical parameters
• Mechanical dimensions
• Recommended soldering conditions
• Test conditions
• Product photographs
• Sample evaluation
• Packaging information
• Production and delivery confirmation

Optical values should always be compared under the same current, pulse width, duty cycle, temperature and measurement method.

Export and Project Process

1. Submit the wavelength and application requirements.
2. Confirm the detector, working distance and optical target.
3. Select a standard product or evaluate a custom design.
4. Review the datasheet and available test information.
5. Order samples for system verification.
6. Test the LEDs with the intended samples and detector.
7. Confirm the final specification and production quantity.
8. Arrange production, inspection, packaging and export.

Why Work Directly with a Chinese SWIR LED Manufacturer?

Working directly with the manufacturer can provide:

• Faster technical communication
• Access to standard and custom wavelengths
• Package and lens customization
• Prototype-to-production support
• Flexible order quantities
• PCB, COB and module integration
• Direct specification confirmation
• More efficient supply-chain coordination

The supplier should still be evaluated based on documented specifications, test conditions, sample consistency, traceability and communication—not price alone.

Foire aux questions

What SWIR wavelengths can Yingfeng export?

Yingfeng can supply or evaluate SWIR LED requirements from approximately 1000nm to 1900nm. Availability varies by wavelength, chip, emballer, output requirement and quantity.

Can Yingfeng customize a SWIR LED wavelength?

Custom target wavelengths and wavelength tolerances can be evaluated. Feasibility depends on chip availability, binning requirements, optical output and production volume.

Can I order SWIR LED samples before mass production?

Sample evaluation is recommended before volume production. Customers should test the LEDs with their actual camera, detector, filter, sample and working distance.

Does Yingfeng supply 1450nm SWIR LEDs?

1450nm SWIR LED products can be evaluated for applications such as moisture and water-related inspection. Detection results must be verified under the customer’s actual system conditions.

Can Yingfeng supply 1700nm and 1900nm SWIR LEDs?

Products or custom projects at longer SWIR wavelengths can be discussed. Optical output, detector compatibility, thermal design and availability should be confirmed during engineering review.

Which camera should be used with a SWIR LED?

Applications above 1000nm commonly use an InGaAs camera or another detector with verified sensitivity at the selected wavelength. Review the detector’s spectral-response curve before selecting the LED.

What information is required for a quotation?

Provide the target wavelength, quantité, application, detector, working distance, illuminated area, drive mode, optical target and package requirements.
