SWIR LED

Marubeni is proud to present its new line of High Power SWIR LEDs.

Our SWIR LEDs feature the highest power in today's market. Various lenses are available to meet your specific viewing angle requirements (+/-10 degrees - +/-60 degrees), including our ultra-sharp 02 lens which is a rarity in the market. Other advantages include:

  1. High  power – highest in the industry
  2. Excellent stability over time (life characteristics)
  3. Various wavelengths available in a wide range (1050-1750nm)
  4. Narrow peak wavelength tolerance (+/-20nm)
  5. Custom wavelengths are available based on your specific requirements

SWIR (Short Wavelength Infrared) LED features:

  • Light absorption of specific substances (Water, protein, alcohol, fatty acid, glucose, etc.)
    • Applications: Grain Inspection, Vital Sensor, Medical devices, Road Surface Freeze Sensor
  • Silicon wafer/substrate transmission
    • Applications: Solar Panel Inspection, Si Device Inspection 
  • Water vapor and fog transmission
    • Applications: Night Vision, Security Camera Lighting
  • Light source of SWIR wavelengths (1050-1750nm) 
    • Applications: Sun simulator light source

Available in Various Wavelengths

 

A line graph shows the relative radiant intensity (in arbitrary units, A.U.) versus wavelength (in nanometers, nm) for various wavelengths ranging from 10500 to 17500. The graph contains multiple colored peaks, each representing a different wavelength. SWIR LED wavelengths.

*Various wavelength are available to meet your specific requirements

Available Packages and Radiation Characteristics

 

SWIR LED Radiation Characteristics and Package Types. A collection of six LED lens diagrams showing radiation characteristics. Descriptions include SMBB Flat (±60°), SMBB 02 Lens (±10°), EDC Flat (±60°), SMBB 03 Lens (±30°), SMBB 05 Lens with "To be confirmed" label, and EDC S5 Lens (±40°).

LED Performance Improvement (Compared to existing SWIR LEDs)

 

Highlights:

  • Light output increases 2-4 times compared to older generation SWIR LEDs
    • Newly designed SWIR LEDs significantly increase output power (the increase varies depending on the wavelength)
  • Maintains higher light output when driven at large current

SWIR LED performance comparison. The image has two graphs comparing performance metrics of versions of a device labeled "SMBB." The left graph compares total radiated power (mW) versus peak wavelength (nm) for S-version and D-version. The right graph shows power output (mW) versus pulse current (mA) for current and new structures.

SWIR-LEDs - With Decreasing Price of the InGaAs Camera, New Applications Arise

 

SWIR LED - new applications. A diagram shows different wavelengths from 400 nm (violet) to 2.5 μm, dividing them into Visible, NIR (near-infrared), and SWIR (short-wavelength infrared) ranges. It features LEDs, including SWIR LED types, and image sensors, specifying materials used like GaAs, InP, AlInGaN, and InGaAs.
