SWIR LED Chips (970-1700nm) — Advanced Short-Wave Infrared Solutions

Product Overview

QUEENDOM’s SWIR LED Chips deliver cutting-edge short-wave infrared illumination for demanding industrial and scientific applications. Operating across the critical 970-1700nm wavelength range, these semiconductor light sources enable precise material discrimination, defect detection, and spectral analysis that visible-light systems cannot achieve.

Short-Wave Infrared (SWIR) technology has revolutionized quality control in food processing, polymer identification in recycling facilities, and wafer-level inspection in semiconductor manufacturing. Our SWIR LED chips provide the spectral precision, thermal stability, and optical power required for these high-value B2B applications.

Key Applications

Food Sorting and Quality Control

SWIR illumination at 1450nm and 1550nm penetrates fruit and vegetable skins to reveal internal bruising, rot, and foreign objects invisible to RGB cameras. QUEENDOM SWIR chips power high-speed sorting lines for apples, potatoes, onions, and stone fruits, delivering >99.5% defect detection accuracy at conveyor speeds exceeding 3 m/s.

Plastic and Polymer Recycling

Different polymer types (PET, HDPE, PVC, PP, PS) exhibit unique SWIR absorption spectra between 1000nm and 1700nm. Our SWIR LED chips enable real-time NIR spectroscopy systems that automatically sort mixed plastic waste streams with >95% purity, directly supporting circular economy initiatives and EPR compliance for packaging manufacturers.

Semiconductor Wafer Inspection

At 1050nm and 1200nm, silicon becomes partially transparent while crystalline defects remain absorbing. QUEENDOM SWIR chips illuminate automated optical inspection (AOI) systems for silicon wafer quality control, detecting micro-cracks, voids, and doping irregularities at sub-micron resolution.

Security and Night Vision

SWIR illumination is invisible to human eyes and most consumer cameras, making it ideal for covert surveillance, perimeter security, and driver monitoring systems. Our 1550nm chips pair with InGaAs sensors to deliver clear imaging through haze, smoke, and light fog where visible-light systems fail.

Frequently Asked Questions

Q: What is the minimum order quantity for SWIR LED chips?

A: Standard SWIR chips require MOQ of 500-1000 units depending on wavelength and package. Custom wavelengths or special ceramic substrates may have higher MOQ. Sample quantities (10-50 units) are available for qualified B2B partners at standard catalog wavelengths.

Q: Can you customize the peak wavelength beyond the 970-1700nm range?

A: Yes. While 970-1700nm covers the most common InGaAs detector sensitivity range, we can engineer chips from 850nm (NIR) through 2200nm (extended SWIR) using different semiconductor compositions. Contact our application engineering team with your target wavelength and optical power requirements.

Q: Do you provide optical sub-assemblies or just bare chips?

A: We offer multiple integration levels: bare die, chip-on-board (COB), SMD ceramic packages, and complete optical sub-assemblies with integrated lenses, heat sinks, and driver electronics. This flexibility allows you to integrate at whatever level matches your manufacturing capabilities.

Q: What thermal management is required for high-power SWIR arrays?

A: At optical power >1W, active cooling (heat sink + thermal interface material) is recommended. Our ceramic packages are compatible with standard pick-and-place and reflow processes. We provide thermal simulation support and can recommend specific heat sink geometries based on your operating conditions.

Q: How do I request samples or a formal quotation?

A: Submit your requirements through our website contact form or email sales@queendomlamp.com directly. Please include: target wavelength, optical power requirement, package preference, estimated annual volume, and application description. Our technical sales team responds within 24 hours with specifications, pricing, and sample availability.
