NIR Reflectance Measurements of Small Leaves and Pine Needles

Capturing reflectance data of small vegetation samples such as pine needles, blades of grass, and tiny leaves can be challenging. The very small field of view needed for the measurement, as well as the required high sensitivity of the spectrometer can be obstacles to obtaining quality data.

NIR Reflectance Measurements of Small Leaves and Pine Needles

As a trade-off, researchers have taken the habit of measuring the combined spectrum of many small samples bunched together However, the resulting spectrum represents an average of the spectral features of all samples, not necessarily the individual trait of each sample.

Capturing the individual spectrum of a single small sample is now possible with Spectral Evolution’s innovative small sample adapter. The adapter, combined with Spectral Evolution’s unique Leaf-clip Reflectance Probe, and the high-sensitivity of the NaturaSpec™ UV-Vis-NIR spectroradiometer allows researchers to measure precise reflectance data over the spectral range of 350nm to 2500nm.

Our leaf clip is specifically designed for leaf reflectance measurements. It features an innovative design that provides a streamlined and effective approach for scanning vegetation — including leaves and pine needles — while ensuring that the sample is not harmed. Our unique design puts the integrated light source further away from the sample to minimize heat damage. The leaf clip design features a swivel head that provides a built-in white reference.

The NaturaSpec™ spectroradiometer offers the best resolution and sensitivity performance of any field instrument on the market today. You can now collect lab-quality data under any condition over the full spectral range of 350nm to 2500nm. With a rugged design, no moving optical parts, and a stainless-steel clad fiber optic cable, you can now expect outstanding stability and reliability of spectral measurements in the field. NaturaSpec™ is sold as a bundle so you can start gathering your mission-critical data without delay.
