LWIR Spectral Cameras

LWIR 8 - 14 μm

Thermal Hyperspectral Cameras in The long Wave Infra Red (LWIR)

LWIR Spectral Cameras are pushbroom type line scan cameras that provide full, contiguous hyperspectral data for each pixel along the imaged line. To respond to a wide range of applications and requirements. We have developed 3 models of LWIR Spectral Cameras; HS and HR (with uncooled detectors) and C (with cooled detector)

HS and HR Models

Spectral Cameras LWIR HS and HR integrate an uncooled detector and optics. They are compact and light weighing only 3.5 kg and are versatile tools for a wide variety of applications.

HS (high sensitivity model) covers the range 8-14μm. With a good sensitivity and moderate spectral resolution, HS is suitable for many industrial and Chemical Imaging applications.

HR(high resolution model) covers the range of 8-14μm and is designed for applications that require high spectral resolution. With spectral sampling of 70 nm and 85 bands, HR is a solution for applications where the targets emit at higher than normal ambient temperatures or where an IR source is used to illuminate the sample. Application examples include gas emission analysis and infrared Chemical Imaging.

C model

For the most demanding ground based remote sensing and security applications, Gilden Photonics has integrated a state-of-the-art temperature stabilized LWIR imaging spectrograph with the highest sensitivity cooled MCT detector. Spectral Camera LWIR C covers the spectral range 8-12um with high spectral selectivity of 84 bands (sampling of 48nm) and extensive speed of up to 100 images.
