LWIR spectral camera
Hyperspectral imaging in the longwave infrared (LWIR) band offers new ways to identify and quantify even more materials based on their characteristic spectral signatures. Thermal LWIR spectral imaging covers the range 8 – 12 µm and is widely used to analyze chemicals, gases, minerals or atmospheric radiations. Specim is the first manufacturer to have developed push-broom devices for hyperspectral imaging in the LWIR. They use brand-new imaging spectrometers with reflective and refractive optics.
|Spectral band: 8-12 µm|
|Cooled or uncooled detector|
|High spectral and spatial resolution|
|Robust and compact design|
Specim’s LWIR spectral cameras allow measurements under laboratory conditions where illumination is required and line illumination is the best possible choice. Two different LWIR spectral camera detector types are offered: the compact model HS based on uncooled microbolometer technology and the high-performance cooled model C.
The innovative Specim LWIR cameras combine high quality with easy handling especially in regards to illumination. We use a specially designed imaging spectrograph and dedicated optics to offer high transmission while minimizing optical aberrations.
Camera model HS covers the full LWIR wavelength range of 8 - 12 µm. It uses the integration of our spectrograph design with an uncooled microbolometer-based detector. Its spatial resolution is 384 pixels; spectral data is collected in 30 bands and with a spectral resolution of 400 nm. Spectral sampling is 150 nm per band. The acquisition speed is 60 Hz.
Camera model C is used for hyperspectral imaging in the full range from 8 to 12 µm. The highly sensitive camera is based on a cooled longwave MCT detector. The optics are cooled to support highest stability over time, especially during long acquisition runs. The camera offers a spatial resolution of 384 bands and a spectral resolution of as good as 100 nm. Spectral sampling is 48 nm per band. The camera runs with a frame rate of up to 100 frames per second.
