VNIR and TIR spectrophotometer

A Bruker Vertex 70 VNIR and TIR spectrophotometer

Instrument is a fourier transform infrared spectrometer (FTIR) that allows the measurement of reflectance and emissivity spectra in the thermal infrared (MWIR and LWIR) between 2.5 to 16 µm at typically 4 cm-1 resolution. Samples are typically solids, like rocks or soils, but also leaves or eggshells have been measured in the past.

The integrating sphere helps to achieve measurements of absolute directional-hemispherical diffuse reflectance which are directly comparable to emissivity spectra acquired from e.g. airborne or spaceborne sensors.

Hyperspectral camera’s

Specim Hyperspectral camera’s: Two hyperspectral cameras (imaging spectrometers): One measures in visible – near infrared light (350 – 1000 nm) in 768 spectral bands and 1024 spatial pixels; the other measures shortwave infrared light (1000 – 2500 nm) in 288 spectral bands and 384 spatial pixels. Depending on the choice of accessories, the cameras can scan an image of a stationary target in the laboratory or scan scenery in the field. Hyperspectal cameras are sensitive to chemical composition, and serve applications in chemistry, geology, water and plant sciences.

MIDAC

A MIDAC thermal range FTIR field spectrometer with fore optics and liquid N2 cooled MCT detector

The MIDAC Illuminator (Model M4401-F) is a fourier transform infrared spectrometer (FTIR) that allows the measurement of emissivity spectra in the thermal infrared (MWIR and LWIR) indoors and outdoors with spectral range of 2.5 to 20 μm and an adjustable spectral resolution of 32 to 0.5 cm-1. Samples can vary from rocks to plant canopies and soils.

Mineral Identifier

Terraspec halo mineral identifier: all-in-one mineral analysis system that allows you to immediately identify alteration minerals with a simple pull of a trigger. The TerraSpec Halo mineral identifier is a full-range NIR spectrometer measuring the visible and short wave infrared regions (350-2500 nm) that produces immediate on-instrument results using a non-destructive contact measurement.

FLIR

The FLIR X6570sc thermal imaging camera provides superior thermal measurement performance paired with the most advance connectivity. Whether you need to analyze hight-speed processes with microsecond precision or monitor fast temperature spikes, the X6570sc has the integration time and frame speed needed to collect the most accurate data. In addition, the camera's state-of-art connectivity and intuitive user experience allow researchers to focus on their experiments instead of the camera controls.
