What is SWIR good for?

SWIR imaging is used in a variety of applications including electronic board inspection, solar cell inspection, produce inspection, identifying and sorting, surveillance, anti-counterfeiting, process quality control, and much more.

What can SWIR see?

SWIR can image through glass or plastic windows something that MWIR and LWIR can not. SWIR also has the ability to use reflected light as well as emitted light enabling one to more easily differentiate objects.

Does SWIR work at night?

On the other hand, a single SWIR camera can be used for both day and night imaging. In an Unmanned Aerial Vehicle (UAV), for example, this single camera can operate over the full duration of typical long day/night mission profiles.

Can SWIR see through clouds?

Short Wavelength Infrared (SWIR) These imagers have the ability to capture clear detail through smog, clouds, and haze. SWIR cameras are the only wavelength technology that can penetrate cloud coverage and capture a clear image.

What does short wave IR mean?

Short Wave IR (SWIR) is a subset of the infrared band in the electromagnetic spectrum, covering the wavelengths ranging from 1.4 to 3 microns. This wavelength is not visible to human eyes and as a result can often offer a better image than what is achievable with visible light imaging.

What is short wavelength infrared?

Shortwave infrared (SWIR) light includes wavelengths between 1,100 and 3,000 nanometers. Water absorbs shortwave infrared light in three regions: 1,400, 1,900, and 2,400 nanometers. Active fires, lava flows, and other extremely hot features “glow” in the shortwave-infrared part of the spectrum.

What is short wave infrared?

What is short infrared?

Does water absorb near infrared?

Near infrared (NIR) light includes wavelengths between 700 and 1,100 nanometers. Water absorbs NIR, so these wavelengths are useful for discerning land-water boundaries that are not obvious in visible light. Water absorbs shortwave infrared light in three regions: 1,400, 1,900, and 2,400 nanometers.

What band is short wave infrared?

What is short wave infrared ( SWIR ) used for?

Short-wave infrared (SWIR) defines a specific wavelength range over which optical and electronic components are designed and coated. SWIR imaging offers a number of advantages compared to visible when used for inspection, sorting, surveillance, quality control, and host of other applications.

What is the wavelength range of SWIR light?

What is SWIR? Short-wave infrared (SWIR) light is typically defined as light in the 0.9 – 1.7μm wavelength range, but can also be classified from 0.7 – 2.5μm. Since silicon sensors have an upper limit of approximately 1.0μm, SWIR imaging requires unique optical and electronic components capable of performing in the specific SWIR range.

Are there any smart lights that use SWIR?

These lights perfectly complement the recently introduced Sony IMX990 and IMX991 SenSWIR line of cost-effective imaging sensors as well as the quantum-dot SWIR Vision Systems CQD sensor line.

What kind of sensors are used in SWIR imaging?

Since silicon sensors have an upper limit of approximately 1.0μm, SWIR imaging requires unique optical and electronic components capable of performing in the specific SWIR range. Indium gallium arsenide (inGaAs) sensors are the primary sensors used in SWIR imaging, covering the typical SWIR range, but can extend as low as 550nm to as high as 2.5μm.
