  • Leaf Porometer for stomatal conductance

    The SC-1'sgets accurate stomatal conductance measurements practical for everyday research. It leaves the environment alone, and instead determines stomatal conductance by measuring the actual vapor flux from the leaf through the stomates and out to the environment.

  • Leaf area meters

    Several leaf area meters are available:

    The ADC AM350 Portable leaf area meter is a compact, user friendly, field portable instrument for the accurate non-destructive measurement of leaf area and associated parameters. The AM350 consists of a high resolution scanner and scanboard with integral data and image storage. A multi positional carrying handle is provided for ease of use and increased portability. Measurements of leaves can be made on the scanboard plate or on an independent plain surface.

    The LI-3000C combines an easy-to-use readout console with the proven scanning technology of the LI-3000C sensor head to provide a powerful system for portable, non-destructive leaf area measurements. It utilizes an electronic method of rectangular approximation to provide 1 mm2 resolution. Leaf area, leaf length, average width, and maximum width are logged by the readout console as the scanning head is drawn over a leaf. Files can be viewed on the display or output to a computer using the LI‑3000C application software.

    The LI-3100C Area Meter is designed for efficient, exacting measurements of both large and small objects. User-selectable area resolution of either 1 mm2 or 0.1 mm2 is available without having to change optics. This versatility provides the flexibility necessary for diverse project requirements.

  • Plant canopy analyzers

    Multiple versions of plant canopy analyzers are in the lab:

    Leaf Area Index (LAI) measurements, such as those taken by the LAI-2000 or the LAI-2200/C, can be used to determine treatment effects, crop progression, and seasonal variation, to name a few parameters.

    The process of obtaining LAI measurements can be very simple.  To generate a value for LAI, take a series of Above and Below canopy readings, repeating as many times as needed to develop statistical robustness.   The process of interpreting them, however, can be more complex.

  • 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.

  • TLS

    The RIEGL VZ-400 3D Terrestrial Laser Scanner provides high speed, non-contact data acquisition using a narrow infrared (1550 nm) laser beam and a fast scanning mechanism. Typical applications include forestry, city modelling, civil engineering, architecture measurement, archaeology and cultural heritage documentation.

    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.
